Are these magnet reef and glass safe?

Hello, I’m trying to find some magnets to hold my screen lid in place. Are these ones safe to use on glass or will they be too strong?

My glass is about 1/4” thick

retracting my first comment,

it does say waterproof in their description, I'd trust it, or you can cover it in silicone to be 99% sure.
