The positioning board on the keyboard is painted off.

What is more practical is what kind of transparent glue is attached to the commonly used letters or numeric keys.

If it still doesn't look good, buy a keyboard film and stick it on it. Or you still feel bad. The next time you buy a keyboard, buy letters and numeric keys with plastic protective layers on them.

There is no good way. If you really can't stand it, you can put up some cartoon stickers, such as keyboard stickers. Or buy keyboard paint and spray it on. Buy the same color as the notebook. Pay attention to cover up the places you don't want to spray before spraying.
