Molshine Compatible Heat Shrink Tube Label Tape, Replacement for Brother HSe221 HSe-221 HS221 HS-221 Black On White 9mm x 1.5m (3/8 inch x 4.9 feet), 10 Pack

Beware! The $32 price is great for a 10-pack, but outrageously high for the 2-pack they actually send you! The 2-pack is labeled "10 Pack" but only contains 2 cartridges.
