Snaps are compliant with CPSC CPSIA standards regarding lead content in children's products.
NOT COMPATIBLE WITH THE KAM PLIERS SOLD ON AMAZON (which only work with plastic snaps). Can be installed with KAM table-top professional presses with corresponding dies or KAMsnaps® KX6 multi-functional hand pliers. Can also be installed with hammer method, including with Snap Source setter.
Approx 7/16" (10mm) diameter. Cap prongs are approx 3mm long, sufficient for most sewing fabrics but not intended for use with thick or dense fabrics.
Thin or stretchy fabric like knits and jersey must be reinforced with sturdier material around the area of snaps to avoid ripping (this is true with all snaps).
