Product Overview
Each A6-sized Col-o-ring Oversize features 40 sheets of 100lb/160gsm acid-free European paper, sturdy chipboard covers, and a plastic spiral ring for convenient storage. With a larger sheet size, slimmer profile, and durable spiral binding, it provides 80 square inches more paper per book, ideal for ink and mixed media use.
Originating from Kansas City, these books were designed, printed, and assembled locally, with the paper sourced from nearby distributors. Born out of the discontinuation of a favored Japanese ink testing product, the Col-o-ring was conceived by its creators in October 2016. After extensive testing, they settled on the current paper stock in January 2017, selecting chipboard covers and a retro-inspired name to ensure timelessness and versatility for users' needs.
