Features 1. NO GLUE, NO STICKING REQUIRED: The piano notes guide is made of silicone and connects the labels in series, eliminating the need to adhere directly to keys like traditional piano stickers. Easy to install and remove without leaving residue, keeping your keyboard clean. 2. DOUBLE STAFF DISPLAY: Displays each key's note on both treble and bass staves, helping users quickly locate the correct key, as most piano sheet music uses this standard notation system. 3. IDEAL FOR BEGINNERS: No prior knowledge of key names or Middle C location is needed. Simply place the note strips on the piano keyboard for immediate use. 4. REMOVABLE AND REUSABLE: Once you become familiar with the keyboard layout and octave positions, you can remove the strips. Reapply them anytime if additional guidance is needed. 5. FITS 88-KEY FULL-SIZE KEYBOARDS: Compatible with standard 88-key pianos, including grand pianos, upright pianos, and digital pianos.
