The will hold two Twelve Grams snugly and most importantly in total silence.
Four internal O-Rings provide 12 Gram retention.
And once you dump your empty 12 Gram you just put your bucket changer under a fresh 12 gram and pop it in with a thumb.
O-Rings for 12 Gram retention are included.
Add a single drop of oil on each O-Ring if desired to loosen the grip on your 12ies.
