A BOK is an accessory that makes the reading experience easier for readers by fitting onto the thumb and placing it in the middle of the book, causing its pages to spread out so that it remains open without effort.

It is a different and novel way to accompany your best readings. Made from materials with organic components such as corn starch and sugar cane, this bioplastic, unlike other polymers that decompose in hundreds of years, manages to decompose in 5 to 7 years under the right conditions.
