The TWSBI ECO is a piston filler that holds about 1.76 ml of bottled ink and has a clear barrel. The LAMY safari takes T10 cartridges or a Z28 converter and has swappable nibs, including a left-hand nib. Pick the safari as a first pen, the ECO for bottled ink. - URL: https://stationerytimes.com/guides/twsbi-eco-vs-lamy-safari/ - Category: Pens - Author: Ellis Penhale - Published: 2026-10-22 - Updated: 2026-10-22 ![Clear TWSBI ECO (167.5 mm posted, piston rod visible, about 1.76 ml) above a charcoal LAMY safari (163.9 mm posted, ink window, T10 cartridge or Z28 converter), drawn to one scale, with an inset of a twist-knob piston](https://stationerytimes.com/images/raster/twsbi-eco-vs-lamy-safari-16x9.png) *Both posted, to scale at 1 mm = 3.4 px, from Goldspot and Goulet Pens measurements.* Original drawing (SVG): .

The [TWSBI ECO](https://stationerytimes.com/guides/twsbi-eco/) comes from TaShin Precision of Taiwan and launched in 2015. The [LAMY safari](https://stationerytimes.com/guides/lamy-safari/) was designed in 1980 and is made in Heidelberg by LAMY, now part of Mitsubishi Pencil. ## How do the specs compare? **The ECO holds more ink and is a little heavier; the safari has more nib choices and a shaped grip.** | | TWSBI ECO | LAMY safari | |---|---|---| | Filling | Built-in piston, bottled ink only | LAMY T10 cartridge or Z28 converter | | Ink per fill | About 1.76 ml (Goulet) | T10 1.1 ml (JetPens); Z28 about 0.8 ml | | Steel nibs | EF, F, M, B, 1.1 mm stub | EF, F, M, B, LH; 1.1 and 1.5 mm italics | | Nib swaps | No ECO nib unit sold | Push-on nibs, swap by hand | | Grip | Clear, no molded flats | Molded tripod flats | | Capped | 138.8 mm (5.5 in) | 139.5 mm (5.5 in); LAMY: 144 mm | | Posted | 167.5 mm (6.6 in) | 163.9 mm (6.5 in) | | Weight | 21 g | 17.0 g; LAMY: 16 g | | Cap | Screw-on, with an inner cap (TWSBI) | Postable, spring clip (LAMY) | | Made in | Taiwan (Goldspot) | Germany (LAMY) | | Price band | $$$ ($20–75) | $$$ ($20–75) | ECO measurements are Goldspot's and Goulet Pens'; safari measurements are Goulet Pens', with LAMY's own figures where they differ. ## How much ink does each one hold? **The ECO holds the most, more than double a Z28 converter, because the whole barrel is the ink tank.** You dip the nib in a bottle and turn the knob at the end, and the piston draws ink into the barrel. ![Ink per fill to scale at 1 ml = 200 px: TWSBI ECO piston 1.76 ml (Goulet Pens), LAMY T10 cartridge 1.1 ml (JetPens; Galaxus 1.25 ml), LAMY Z28 converter about 0.8 ml](https://stationerytimes.com/images/twsbi-eco-vs-lamy-safari-capacity.svg) *A T10 cartridge holds more than the safari's converter, but only in LAMY's colors.* The safari is easier day to day: push in a cartridge and write. Its [Z28 converter](https://stationerytimes.com/guides/lamy-z28-converter/) opens up bottled ink, though it holds less than a cartridge. Capacity figures vary by source. JetPens lists the T10 at 1.1 ml and Galaxus at 1.25 ml, while Goulet Pens' AL-star page gives 1.56 ml with a cartridge and 1.08 ml with the converter, so treat the LAMY numbers as approximate. ## Which has the better nibs? **The safari, on choice and convenience; the ECO, if you want a stub.** LAMY's steel nibs push on and pull off by hand, so one pen can wear an EF today and a 1.5 mm italic tomorrow, and LAMY makes a left-hand (LH) nib. TWSBI sells the ECO with five nib widths, including a 1.1 mm stub, but no separate ECO nib unit. Pure Pens says a Diamond Mini nib unit can be moved across with care. Our [fountain pen nib sizes](https://stationerytimes.com/guides/fountain-pen-nib-sizes-explained/) explainer compares typical widths. ## Which is more comfortable to hold? **It depends on your grip: the safari's molded flats suit a standard tripod grip, while the ECO's clear grip has no flats to fight.** Wikipedia describes the safari's grip as non-round and shaped for a tripod grip, so writers who hold a pen differently should try one first. The ECO is 4 g heavier and its posted length is 3.6 mm longer. Both caps post, and the ECO's screw-on cap seals with an inner cap, per TWSBI. ## Which should you buy? **Pick the LAMY safari if it's your first fountain pen, you want cartridges, a left-hand nib or nib swaps; pick the TWSBI ECO if you already use bottled ink, want the biggest ink supply or like a clear demonstrator.** - **LAMY safari:** the easier start. Add a Z28 later for bottled ink, such as LAMY's [T52 ink](https://stationerytimes.com/guides/lamy-t52-ink/). - **TWSBI ECO:** budget for a bottle too, since it can't take a cartridge. It comes with a wrench and silicone grease for the piston. - **Also consider:** our [Pilot Metropolitan vs LAMY safari](https://stationerytimes.com/guides/pilot-metropolitan-vs-lamy-safari/) comparison sets the safari against a heavier brass pen, and the [best fountain pens for beginners](https://stationerytimes.com/guides/best-fountain-pens-for-beginners/) roundup ranks more starter pens. For filling and flushing either pen, see [how to fill a fountain pen](https://stationerytimes.com/guides/how-to-fill-a-fountain-pen/). ## Frequently asked questions ### Is the TWSBI ECO or the LAMY safari better for beginners? The safari, for most people. It works out of the box with a cartridge, nibs swap by hand and there's a left-hand nib. The ECO suits beginners who already want bottled ink and a big ink supply. ### Can you use cartridges in a TWSBI ECO? No. The ECO fills only from a bottle with its built-in piston and doesn't accept cartridges or a converter, according to JetPens. ### Does the LAMY safari come with a converter? Usually not. The safari normally comes with one blue T10 cartridge, and the Z28 converter is sold separately for bottled ink. ### Can you swap nibs between the ECO and the safari? No. LAMY's push-on steel nibs fit LAMY pens, and TWSBI doesn't sell a separate ECO nib unit; Pure Pens says a TWSBI Diamond Mini nib unit can be moved into an ECO. ### Which holds more ink, the ECO or the safari? The ECO. Goulet Pens lists it at about 1.76 ml, against 1.1 ml for a LAMY T10 cartridge (JetPens) and about 0.8 ml for the Z28 converter. ### Which is heavier, the TWSBI ECO or the LAMY safari? The ECO, slightly: 21 g per Goldspot and Goulet Pens, against 17.0 g for the safari per Goulet Pens (LAMY Germany lists 16 g). ### Where are the TWSBI ECO and LAMY safari made? The ECO in Taiwan, per Goldspot's spec sheet; the safari in Heidelberg, Germany, per LAMY's own listing. ## Sources - [TWSBI: ECO Clear Fountain Pen (official store: nib choices, postable cap, US$36.99 on October 20, 2026)](https://www.twsbi.com/products/twsbi-eco-clear-fountain-pen) - [LAMY (Germany): LAMY safari Füllhalter (€22.90, ASA plastic, steel nib EF–B and LH, 144 mm, 16 g)](https://www.lamy.com/de-de/p/lamy-safari-fullhalter/54912096764248) - [LAMY: LAMY safari fountain pen (country of origin Germany, manufacturer)](https://www.lamy.com/en-in/p/lamy-safari-fountain-pen) - [Goldspot: TWSBI ECO fountain pen, Black (dimensions, 21 g, wrench and grease, made in Taiwan)](https://goldspot.com/products/twsbi-eco-fountain-pen-in-black) - [Goulet Pens: TWSBI ECO fountain pen, Clear (dimensions, 21.0 g, 1.76 ml)](https://www.gouletpens.com/products/twsbi-eco-fountain-pen-clear) - [Goulet Pens: LAMY safari fountain pen, charcoal (measurements)](https://www.gouletpens.com/collections/lamy-safari-fountain-pens/products/lamy-safari-fountain-pen-charcoal) - [Goulet Pens: LAMY Z28 cartridge converter (0.8 ml)](https://www.gouletpens.com/products/lamy-z28-cartridge-converter) - [JetPens: LAMY T10 Blue ink, 5 cartridges (capacity 1.1 ml)](https://www.jetpens.com/LAMY-T-10-Blue-Ink-5-Cartridges/pd/1923) - [Goulet Pens: LAMY AL-star fountain pen, Graphite (1.56 ml with a T10 cartridge, 1.08 ml with the converter)](https://www.gouletpens.com/lamy-al-star-fountain-pen-graphite) - [Galaxus: LAMY T10 ink cartridges (1.25 ml)](https://www.galaxus.at/en/s12/product/lamy-ink-cartridges-t-10-blue-5-pcs-ink-refills-ink-cartridges-8059208) - [JetPens: TWSBI ECO Caffe Bronze, Fine (bottled ink only, wrench and grease)](https://www.jetpens.com/TWSBI-ECO-Caffe-Bronze-Fountain-Pen-Fine-Limited-Edition/pd/42697) - [Pure Pens: TWSBI Diamond Mini replacement nib unit (also fits the ECO once removed from its collar)](https://www.purepens.co.uk/collections/all/products/twsbi-diamond-mini-replacement-nib-unit) - [Goldspot: TWSBI ECO fountain pen overview (introduced 2015)](https://goldspot.com/blogs/magazine/twsbi-eco-fountain-pen-overview) - [Wikipedia: Lamy (safari grip shaped for a tripod hold)](https://en.wikipedia.org/wiki/Lamy) - [Museum Boijmans Van Beuningen: Safari (1980, Wolfgang Fabian)](https://www.boijmans.nl/en/collection/artworks/110383/safari)
