Generic Waterproof Adhesive Tape
Ordering everything online can be annoying; it’'d be nice to go to a local store and just buy what you need. There are no Asian music supply stores in the area so I tried a generic Waterproof Adhesive Tape from a drug store. The adhesive is weak, the backing is stiff, and after a week of use I would not recommend it for guzheng use.
It's a 0.5 inch -wide medical tape with serrated edges for easy tearing. That serration is a cool idea that works well. Unfortunately the backing is a rigid plastic. That restricts motion and prevents the fingers from bending how they should.
Don’t buy rigid tapes, they won’t work for you.
