This is a collaboration product with ACE, purchased exclusively online. I am selling it because I changed the size of my planner. There are some scratches on the pen holder from use, but overall, I think it's in good condition.

This material combines lightness, durability, and design, and has a proven track record of reliability. Exterior: Polyester 1680dn Oxford While being lightweight (*), the thick fiber mesh of the 1680dn (denier) polyester material creates high elasticity and the original firmness and body of the fabric.
