These pressure-sensitive adhesive sticky index tabs are great for making your own sections in a notebook. The fold-over tabs have a grid on one side so that you can align it straight along the edge of your page at your preferred depth and it's translucent so you can still see whatever writing is underneath. You can write on them and they are durable and removable.
Each tab measures 1 7/16" tall x 9/16" wide when folded. Comes in a pack of 12 (two each of six colors). Made in Japan.
