Fits the Better Pack BP333 manual gummed tape dispenser. These brushes moisten the tape as it's being dispensed. If you find the tape is 'too wet' and requires a lot of rubbing to get it to stick to the box, the brushes may need to be cleaned.
We recommend removing the tank and brushes two weeks or so, and cleaning the brushes with a mild dish-washing detergent like Dawn. Avoid using detergents with moisturizing additives.
