Keshi (Japanese: 消し or ケシ) aka keshigomu (消しゴム, literally "erase rubber") is the Japanese word for eraser. In modern "keshi" refers to a collectible miniature figure, often of a manga or anime character, made of coloured hard rubber. However, the word's reference has broadened beyond its etymological meaning, as keshi are made of several types of rubber.

NOTE: although it probably goes without saying - as erasers, they’re absolutely terrible.

Not all keshi are created equal — some were sold as boxed/capsule sets, others were bonuses bundled with other merch, some dropped from gashapon machines, some hid inside candy boxes, and others came bundled with full playsets or board games.

Samurai Pizza Cat keshi came in a wide variety of colours, and many characters saw multiple different keshi sculpts, while others were underrepresented… or not even represented at all.

Some were one solid figure, and others had removable parts (wings, tails, weapons, armour, clothing/accessories, etc). Some had bases to help them stand upright (this was very common for the figures that were meant to be board game pieces), others were left with whatever remaining structural integrity their legs/feet still have.

Where these were meant to be toys for children, a lot of the keshi sold on the second-hand market do not include the removable parts, due to how easy they were to lose.
