SHRINK BAND, WHITE, 25MM, 1000/PK
Cellulose shrink bands are a unique way to seal a cassette. They are stored in a liquid filled plastic jar, then removed and placed around the cassette. As the band dries, it shrink and forms a seal.
To use, simply take a handful of bands out of the jar and place on some paper towels. Remove all excess liquid by patting them dry. Then, place around the cassette. The bands will then begin to dry and in a few hours will dry and form a tight seal.
