BEATBIT Piano Notes Guide for Beginner, Removable Piano Keyboard Note Labels for Learning, 88-Key Full Size, Made of Silicone, No Need Stickers, Reusable and Comes with Box (Classic Black）

【NO GLUE, NO NEED STICK】The BEATBIT Note Strip is made of silicone, and connects the labels in series, so there is no need to stick to the keys like piano stickers. Easy-to-install, Easy-to-remove, without leaving any residue, and keeping your keyboard clean and tidy.
【DOUBLE STAFF DISPLAY】Showing the note of each key with double staff, which helps to find the corresponding key from the keyboard faster, because all piano scores use the treble and bass staff structure.
【BEGINNER FRIENDLY】You don't need to know the names of the keys or where the Middle C is, you just need to put the note strips on the piano keyboard. Done in seconds!
【REMOVE ANYTIME, REUSE ANYTIME】When you start to know the keys and become familiar with the octave rule, you can remove the note strips from the keyboard. Of course, if you feel that you are not skilled enough, you can put it back at any time.
【88 KEY FULL-SIZE】Fits standard sized 88/61-key pianos. Perfect for grand pianos, upright pianos, 88/61-key digital pianos and keyboards. Some non-standard size 76/54/49/37-key keyboard instruments may not fit properly. Please confirm the size of your keyboard before purchasing, especially the width of the gap between the top of the black keys and the keyboard shell, which must be wider than 2.4mm(0.1 inches).
