Finally, no more ugly masking tape! We designed these plastic tapes 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. This brown color is more for older students and it cannot be easily seen by the audience. Be careful what you put on your precious instrument. This tape is acid free and will not harm the surface of your instrument. Sold 1 roll in a package of 130" of 1/8"" wide tape, enough for as many as 15 uses.
