Features 1. NO GLUE, NO NEED TO STICK: The piano notes guide is crafted from silicone and connects the labels in a chain, eliminating the need to adhere them to the keys like traditional piano stickers. It's easy to install and remove, leaving no residue while keeping your keyboard neat and tidy. 2. DOUBLE STAFF DISPLAY: It showcases the notes of each key with a double staff format, facilitating a quicker identification of the corresponding key on the keyboard, as all piano scores utilize treble and bass staff structures. 3. BEGINNER FRIENDLY: There's no need to be familiar with the key names or locate Middle C; simply place the note strips on your piano keyboard. It's done in a matter of seconds! 4. REMOVE ANY TIME, REUSE ANY TIME: As you learn the keys and get comfortable with the octave patterns, you can detach the note strips from the keyboard. If you feel you need more practice, you can easily reattach them at any time. 5. 88 KEY FULL-SIZE: Designed to fit standard 88-key pianos. Ideal for grand pianos, upright pianos, 88-key digital pianos, and keyboards. Specification Material: Silicone Color: White Size: 18.5x9.5x1.8 cm Weight: 110g Package Include: 1 Piano Notes Guide
