Violin, Viola, and Cello Fingering Tape. Finally, no more ugly masking tape! And no messy gooey tape like from other companies! Long Beach Music Co. has designed these plastic tapes, here in the USA to make it easier for students to learn fingering positions. This neat, durable tape can be easily and accurately placed on the fingerboard of any string instrument. The black color is for older students and it cannot be easily seen by the audience, but still gives the student a tactile aid. Be careful what you put on your precious instrument - this tape is acid free and will not harm the surface of your instrument. Pack of 3 smaller rolls of red, blue, and yellow.
