Help: How can I protect tumbler design from scratches while keeping it visible?

Hi guys, as an introduction I'm not a crafter but if you guys wouldn't mind, I would love to get some advice about my problem. I have some limited edition tumbler merch from shows/games I like but I never use it because I'm afraid of scratching the design. But not using it defeats the point of having one. So, do you guys have any advice on how I can protect the design but still able to see it? I searched up on google and I got that UV resin will the solution but I never use resin so I'm kind of afraid to use it. So any suggestions? Thanks in advance!
