All of us know yellow glue is the best glue in the world for leather making. But when you paint the glue on, it spills out here and there on zipper.
It is time for changing.
By using this mold, you can paint glue on zipper neatly , nothing is better than that for an OCD.....
There are 2 sizes, one for M4(No.3) zipper and the other one for M6(No.5) zipper.
