100 size 16 caps with long prongs (prong length 6.2mm) discounted to only 50 cents! Long prongs are used when you have very thick layers of fabric, such as prefold diapers. Size 16 caps can also be used with size 20 sockets and studs. While supplies last. Available at http://www.kamsnaps.com/Size-16-Long-Prong-Caps-p277.html
Tip: For the extreme bargain hunter, if you do not need long prongs, you can simply clip the tips off the prong to make them shorter.
