Sold in multiples of 50.
Convert a standard snap into a double-sided snap by adding this pronged male/stud & an extra female in the middle (see last thumbnail image).
Note: this is for the pronged male only. You will still need the other parts of a regular snap to create a complete snap. You'll also need extra female pieces to pair with the pronged male.
Requires a pronged stud die for Pliers or DK-93 Press (sold separately).
WARNING - Loose pieces can present a choking hazard to small children
