Mods. 001 and 002 are the first ones to be born in this project. They are apparently usual blank books only standing out because of the quality of the materials, but the way of fastening the leafs allows to recover them after use without any damage, and replace with new ones of the artist's choice characteristics. The cover is for that reason reused as many times as desired, adding a guaranteed beautiful aging and a life-long lasting strength. “pielipapel” also provides ready folded, complete Aquari paper refills, single packed.
