Negative Positive
Title: wonderful
Review: I used this in middle/high school (20 years ago) to correct my right thumb sliding forward; the only product that worked. It would sometimes slide and wiggle its way under a key, and when it's taken on/off it does leave little scratches. But, now, as a middle school band director, I recommend this to flute students who have the same issue. Corn pads work, but they just look weird on the instrument!
