I originally designed these little card holders to help my mum display table numbers for her kindergarten class — she needed something that the kids were able to see without being too clunky and we couldn't find anything else. They worked so well that I ended up printing a bunch more to use around the house for flashcards, nerf targets, and even playing cards. They’re super quick to print and don’t need supports. Hope you find them as handy as we have!
