Beeswax is easy to find at a fabric store. Seamstresses use it to
tame thread ends. A package sells for around $3. Another source
would be a store like Michael’s Crafts that carries candle-making
supplies.

tearing up the inside of your mouth. I’m on round 4 of braces and I’m
SO happy that there is invisline; much more comfy!
