Clever little product here from aNueNue. There is no sticky adhesive on these - the protectors stick to your ukulele using static, so you can be sure that whilst protecting your instrument you will not be marking the top with adhesive.
The pack includes:
Protector left x1 (16.7 x 7.6 cm)
Protector right x1 (16.7 x 7.6 cm)
Cleaning wipe, Dust-removal cloth and Squeegee card
To fit to your instrument you simply mark out a template and cut the protectors to fit exactly. And if you want to remove them any time - no problem!
