Hi Laurie,
I ordered a test one for myself with my shop logo and information on it. Colour me IMPRESSED! The quality is amazing. I live on my phone, so it's forever being carried around, picked up, put down, shoved in my purse, removed from my purse, and generally being well-used (albeit lovingly and carefully). After 3 months of this, there's not a single flaw or evidence of damage to the printing.
It's thick plastic around the back and sides (Samsung S8+), but the front is open. I can see it providing moderate protection if it lands where the case is, but not on the front.
