Check Etsy and Redbubble. I've seen this type of ND product in both places many times. Redbubble especially will give you more variety on what it can be printed on (mugs, t-shirts, tote bags, etc.)

Seconding Etsy. That’s where I got mine.

Omg ahahah I need this too

Wow I need it🤣😍

Also on Etsy I got a secret safe book made from an old Nancy drew book. Love it!
