Thought I'd post an update. To test it out I ordered a plastic peg game for school agers. It arrived yesterday. The pegs and the part they go into are fine. The back of it is so thin I put my finger through it opening the box.
I'll keep the pegs and pegboard and make a quick frame for it in my shop. Guess it was worth the $2 but I hate getting things for daycare that don't last. Probably won't order for daycare from there again.
