How to store the B paper
Sealed in original bag and box
The B paper is prone to moisture. This means it's beast to keep the B paper in the plastic bag, in the box, within a tub/drawer which stays at room temperature. If stored in a cold environment this may damage the glue and cause patchy transfers.
Throwing in a couple of silica gel packets into the plastic bag can help with the moisture issue.
We advise using the B paper within the time span of 1 year.
