Captain Fizzy Acrylic Caps 4-pack Patent Pending
Captain Fizzy Can Caps grip tight to keep the fizz in. To get off to a good start, reseal a half-full can and leave in the refrigerator for 3-6 hours. Then reseal a 3/4 full can overnight. You can reseal a full or nearly full can, but only temporarily. After an hour or two in the refrigerator the cap may pop off.
