tiptoi spiral binding repairpart

The part between the spiral binding metal and the book cover is quite weak. It's just a thin cardboard.  If the card board breaks, the whole book cover comes of. With this part you can reattach the book cover to the spiral binding. It's for tiptoi books with a spiral binding of 31 rounds. On the other side you can attach it with glue, book tape or zip ties. There are wholes for the zip ties.
