This is an acrylic bookmark with holes. There is a film on both sides just like the acrylic covers. You can use any transparent sticker sheets we have in the shop or just leave plain. I added a small word from one of my label sticker sheets and it's very cute.
I will make a few with black vinyl to see if I will be able to do a few and sell. (More to come)
In the picture I am using the Sienna binder, the acrylic doesn't stick out from the bottom.
