Everything you need to know about the Madam Sew Open Ring Snaps and Pliers

These snap fasteners, press studs or poppers are mechanical fasteners that close or lock with a clicking or snapping sound. As they are no-sew fasteners, they make any project or repair you are working on much simpler. You just need pliers to secure the fastener on your fabric.

The top metal ring of the snaps features an open circle that allows the material to show through the center when the snap is attached to a project.

The snaps are size 15, which is 3/8” (10 mm).  

This set comes with 10 x 15 open ring snaps. There are 10 different colors, 4 parts for each snap, 2 caps (or rings) + 1 stud + 1 socket. With this set you can make 150 snaps. The box contains 600 parts in total.


The snaps can be used for different crafts or mending projects. They are often attached to baby and children's clothing, but they can also be used as closures for lightweight apparel and accessories. Snap them on a bib or a pacifier string or on clothing like onesies or shirts.

These prong style snaps (5 point prongs) are best used with loosely woven or knit fabrics. Use no more than 2 layers of light to medium weight fabric with this size of snaps. They are machine washable, they won’t rust


To assemble a snap you need a ring, a silver socket, a silver stud, a silver back ring and a tool (the pliers) to attach them to your project. You just place a ring and a socket in the pliers, fabric in between and push. Do the same thing with the other ring and the stud and your snap button is ready.

You need good hand-h eld snap pliers to attach these size 15 metal snaps to your projects. The package of the MadamSew pliers tool comes with 2 spare rubber rings for the pliers and a metal rod which you can use to tighten the buttons even more with a hammer. This tool is only compatible with the open ring snaps and not the plastic snaps we also carry in our store.
