The 8-inch plastic twist tie is a good choice if you have run out of the twist ties that come free in our 20 & 50-pound plain top or our 20-pound ice bags on wickets. Maybe you just would like to have extra twist ties on hand. It is always better to have a few extra and not need them than to need them and not have them.
Due to the amount of plastic bag that gathers when you want to close the larger capacity ice bags, this is a proper choice. The 4 and 6-inch twist will not quite work with the 20 or 50-pound, but just barely.
