Oh! O-Rings!

Not onion rings, just O-rings, the highly useful rubber washers you so often need. We’ve got two sets of them, in stylish black, each set with its own hinged, double snap-shut, clear plastic storage case with dividers and identifying signs inside so you’ll know which size is which. You pick: the (233)-piece metric set with (14) sizes of rings ranging from 3mm to 22mm; or the (225)-piece standard set with (16) sizes of rings ranging from 3/32” to 13/16”.
