These handy dowel pins can help keep both halves of three-dimensional silicone molds together while the silicone dries! They'll help prevent displacement, giving you a finer, cleaner finish on your final product.
There are three kinds of of guide type dowel pins (oval, cross, or hexagon), so you can select the best type according to the direction of mold deviation you wish to prevent. The dowel pins are made of ABS plastic, and can be reused if removed carefully from the mold after use.
This set is a total of 16 dowel pins - 4 each of the oval, cross, and hexagon guide type pins, and 4 hold type pins. They come in medium size, measuring approximately 25mm long.
