An auxiliary tool for bonding zipper fabrics and leathers. Zipper corner creases can be perfectly flattened by the direction of folds.

There are two pieces in each set. A relatively thick jig is used as the bottom jig, while another is used as the top jig.

According to the corner radius of your project, find the matching corner radius in the tool, use the corresponding corner radius to flatten the zipper fabric, you can do so by pushing the top jig from its edge against the bottom jig.

There are four common corner radius for wallets in the tool, R10, R12, R15 and R20, provides great convenience in leather working.
Additionally, the top jig has a ruler for pricking iron distance, which is 3.0, 3.38, 3.85 and 4.0mm. This small touch enhances leather work efficiency.
