## What is Tombow MONO Original correction tape?

**It's Tombow's classic side-application correction tape: a small dispenser that lays a strip of dry white film over a mistake, which you can write on at once.** Tombow Europe calls it the original MONO correction tape and the first of its side-action designs.

"Side application" means you hold it like a pen and pull it sideways along a line of text, which suits horizontal writing. It's one of the most-bought correction tapes in the US: the Amazon 10-pack (68720) had 4.7 stars from 17,884 ratings when we checked on October 22, 2026.

Tombow doesn't publish the dispenser's size or weight, so our drawing is in proportion. Recycled-content figures vary by market: Tombow Europe says the housing is 100% recycled plastic, and LDLC, a French retailer, says at least 74% of the plastic parts.

## How wide is the tape on a page?

**At 4.2 mm, the tape covers one line of handwriting with room to spare inside a 7.1 mm college-ruled line.** That makes it a word-or-line corrector, not one for blocks of text.

![Tombow MONO correction tape over one word on college-ruled paper, drawn to scale, with tape lengths](https://stationerytimes.com/images/tombow-mono-correction-tape-width.svg)

*The 4.2 mm tape over writing at 1 mm = 10 px, and tape length per dispenser.*

Ten meters is roughly 46 lines across an 8.5 in (216 mm) page, by our arithmetic. Tombow USA says the tape takes pen, pencil or marker straight away.


## How does it compare with other Tombow tapes and BIC?

**The MONO Original is the classic non-refillable side tape; Tombow's refillable MONO adds 2 m of tape per cartridge, and the [BIC Wite-Out EZ Correct](https://stationerytimes.com/guides/bic-wite-out-ez-correct/) is its main US rival.**

| Tape | Width × length | Refillable | Application |
|---|---|---|---|
| Tombow MONO Original (68620) | 4.2 mm × 10 m | No | Side |
| Tombow MONO refillable (68665) | 1/6 in × 472 in (about 12 m) | Yes, snap-in cartridge | Side |
| BIC Wite-Out EZ Correct | 4.2 mm × 12 m | No | Side |

Tombow USA also sells a MONO Hybrid style and pen-style MONO Air tapes; the light-pulling [MONO Air](https://stationerytimes.com/guides/tombow-mono-air-correction-tape/) has its own guide. If you'd rather lift pencil marks than cover them, a precision eraser like the [Tombow MONO Zero](https://stationerytimes.com/guides/tombow-mono-zero-eraser/) does that job.

## When did Tombow start making correction tape?

**In 1991, with a push-type tape called MONO White Tape MS, according to Tombow's Japanese site.** A year later, in 1992, came its first side-pull tape, the MONO White Tape YK, chosen because it makes horizontal text easier to correct.

Tombow added a 2.5 mm pen-type tape (MONO White Tape PX) in 1995 and the MONO Air, with its lighter-pulling Air Touch system, in 2016. The company says its correction tapes now hold the top share in Japan; the story of the MONO name itself is in our [Tombow history](https://stationerytimes.com/stories/tombow-history/).

## Is the US MONO Original sold in Japan?

**Not under that name: the closest model on Tombow's Japanese site is the side-pull MONO YS, which also holds 10 m of 4.2 mm tape.** Tombow doesn't say the two are the same product, and the YS also comes in 5 mm and 6 mm.

Tombow Japan lists the MONO YS at ¥330 (about US$2.10) with tax and says its plastic is at least 70% recycled. Its usage notes warn that sharp-tipped pens such as mechanical pencils and fountain pens can peel the tape when you rewrite.

## Where is Tombow MONO correction tape made?

**Tombow doesn't say, and none of the US retailer pages we read state a country.** Tombow is a Japanese company based in Tokyo.

Search results for European CT-YT4 listings mention Vietnam, but we couldn't open those pages to check, so look at the pack if origin matters to you.
