Large Peen Pack - Pack of 5 Peens - for #5 Nylon Zips
Now: $5.25 - $6.75
Pack of 5 purse feet, available in nickel and gunmetal. These are 15mm wide at the bottom of the foot. They do NOT come with a metal washer.
I suggest adding a piece of peltex or decovil heavy behind each foot for security. After bending the prongs, you may consider adding either a piece of interfacing or a piece of duct tape over them to protect your fabric.
