What is the Kaweco Standard Converter?
It is a refillable ink reservoir that replaces the cartridges in Kaweco’s longer fountain pens. Kaweco’s page says it goes into the barrel in place of two ink cartridges, so you can fill from a bottle instead.
Kaweco’s converter page describes it as working like a refillable cartridge: it stays in the pen while the nib is dipped in a bottle and ink is drawn up. Our converters guide explains how converters work in general.

Which Kaweco pens does the Standard Converter fit?
Kaweco says it fits its longer pens: the Supra, Special, Student, DIA2 and Perkeo. The product text names those five, and the shop’s “suitable for” filter also lists the Original.
Kaweco’s converter category page splits the range in two: the Mini Converter for the Sport and Liliput series, and the Standard Converter for all larger fountain pens. See our Kaweco Student and Kaweco Perkeo guides for those pens.
How does it differ from the Mini Converter?
The Standard is more than twice as long. Kaweco lists the Mini Converter at 33 mm closed, so it can sit inside the short Sport barrel, and the Standard at 75 mm.
Both prices were read on Kaweco’s converter category page on November 2, 2026. Our Mini Converter guide recorded a different euro figure on October 30, 2026, so Kaweco’s shop pricing may vary by listing or country.
What colors does the Kaweco Standard Converter come in?
Kaweco sells it in 11 knob colors: caramel brown, midnight blue, palm green, paradise blue, pearl black with chrome, pearl black with gold, royal blue, ruby red, smoky grey, summer purple and sunshine orange. The colored part is the knob at the end; the tube, collar and nozzle look the same in Kaweco’s photos.
Kaweco’s product page showed the caramel brown version as unavailable on November 2, 2026. Kaweco also suggests pairing the pearl black converter with its pearl black ink.
How do you fill it?
Seat it in the pen, dip the nib in the bottle and draw the ink up. Kaweco says the converter stays in the pen during filling, and that repeating the filling movement several times raises the amount of ink it takes up.
Kaweco shows a filling video on its tutorials page. We haven’t timed a fill or measured the volume.
How much does it cost?
Kaweco’s own shop listed €8.95 (about US$10) including VAT on November 2, 2026, plus shipping. Yoseka listed US$8.50 the same day, marked out of stock. Both sit in our $$ band ($5–20).
A banner on Kaweco’s shop said on November 2, 2026 that it could not accept orders shipped to the US because of import and customs fees, and pointed buyers to US specialty retailers.
Who is the Kaweco Standard Converter for?
It is for owners of a Kaweco Student, Perkeo, Special, DIA2 or Supra who want to use bottled ink. Kaweco lists these pens for it, so there is no sizing guesswork.
Skip it if you own a Sport or Liliput, which need the Mini Converter, or if your pen is not a Kaweco: Kaweco lists no other brands.
Does it fit pens from other brands?
Kaweco only lists its own pens, so treat other brands as unconfirmed. Yoseka’s tags call it an international-standard converter, but Kaweco’s pages say nothing about other makers.
Check the pen’s section and the converter’s mouth against each other, or read our converters guide first.
Where is it made?
Kaweco doesn’t say. Its product pages list length, weight, material and trim but no country of manufacture, so we leave the origin as not stated.
Frequently asked questions
Does the Kaweco Standard Converter fit the Sport?
No. Kaweco makes the shorter Mini Converter, 33 mm closed, for the Sport and Liliput, and lists the Standard Converter for its longer pens.
Does the Standard Converter work in a Kaweco Student?
Yes. Kaweco's product page names the Student, along with the Supra, Special, DIA2 and Perkeo, and its shop filter also lists the Original.
How big is the Kaweco Standard Converter?
Kaweco lists 7.5 cm (75 mm, 3.0 in) and 3 g. It gives no diameter or ink capacity.
How much ink does the Standard Converter hold?
Kaweco doesn't say. Its page only says that filling several times in a row increases the amount taken up, so treat any capacity figure from a shop as unverified.
Will it fit a Pilot, LAMY or TWSBI pen?
Kaweco lists only its own pens. Yoseka tags it as an international-standard converter, but we couldn't confirm that from Kaweco, so check your pen's section against the converter before you buy.

Kaweco's own shop listed €8.95 (about US$10) including VAT on November 2, 2026, with shipping extra. US shops sell it in our $$ band ($5–20).
Can you reuse the converter?
Yes. Kaweco pitches this as the main advantage over cartridges: it can be refilled again and again, where a cartridge is thrown away once the ink is used.

Yes. Kaweco lists Pearl Black with chrome trim and Pearl Black with gold trim, among 11 knob colors.
