Kuretake Brush Pen for Lettering, Calligraphy, Illustration (AP Certified) Review (2026)

A medium bristle brush tip

This Kuretake pen uses a medium tip marker style brush, built to give expressive, flexible strokes suited to brush lettering, calligraphy and illustration work. The bristle-style construction is designed to hold its shape through repeated use, which is part of why Kuretake brush pens have a reputation for lasting tips compared with cheaper foam or single-fiber alternatives. A medium tip sits between the finest detail pens and the broadest lettering brushes, making it a flexible choice for headline-style lettering as well as moderate detail work like small illustrations or accent strokes on a page. That middle-of-the-road sizing is also why many letterers keep one medium tip pen on hand as an everyday workhorse alongside more specialized fine or broad brush pens.

Refillable black ink

The pen uses black ink and is refillable, meaning the barrel can be reloaded rather than discarded once the initial ink supply runs low. For frequent letterers and illustrators, refillability extends the useful life of the pen and reduces the ongoing cost compared with disposable brush pens that get thrown away after one ink cycle. This is a practical detail for anyone doing daily practice sheets or regular illustration work, since a single reliable brush tip paired with a refill system can outlast several disposable pens over the same period of use. Keeping a small bottle of refill ink on hand also means a pen rarely needs to sit unused while waiting on a full replacement to arrive.

AP certification and safety

The pen carries AP certification, meaning it meets the Art and Creative Materials Institute's standard for non-toxic materials, a certification commonly checked by schools, parents and anyone buying supplies for classroom or shared studio use. This matters less for a solo adult hobbyist working at home but becomes a relevant factor for teachers stocking a classroom or parents choosing pens for a teenager learning lettering. Kuretake, a Japanese stationery maker founded in the early 1900s, applies this certification across much of its brush pen lineup, not just this single model.

Pressure control matters

Like most bristle-style brush pens, this one rewards light, controlled pressure rather than heavy pressing, since bearing down too hard can splay or fray the bristle tip over time and shorten its useful life. New users coming from rigid felt-tip markers sometimes need a short adjustment period to get a feel for how much pressure produces a thick downstroke without damaging the tip. Practicing basic up and down strokes on scrap paper before starting a finished piece is a common way calligraphers build the muscle memory needed to keep a bristle brush tip performing well over time.

Who this pen suits

This pen is a solid pick for someone who already has an idea of what brush lettering feels like and wants one dependable, refillable black brush pen rather than a full multi-color starter kit. The single-pen format means color options are limited to black, so anyone wanting variety for greeting cards or colorful lettering projects will need to pair it with other pens or a set. For classroom use, gifting to a young letterer, or simply replacing a worn-out brush pen with a trusted refillable option, this is a straightforward, focused purchase. Complete beginners unsure whether brush lettering suits them may still prefer starting with a cheaper multi-pen set before committing to a single higher-quality pen like this one.
