Worown 11 Holes Collapsible Plastic Balloon Sizer Box Cube: Efficient Balloon Size Measurement Tool for Stunning Balloon Decorations, Arches, and Columns (2-10 Inch) Review

Really weak but does the job. It's annoying that the tabs break often, but I don't use it all that often.

Definitely useful if you are interested in balloon decor or even planning to make something at home and want it to look the same size. It's thin plastic so I think it will hold up great with careful handling.... Don't force the balls into the hole. There are NO instructions but you can look at the pictures on the product page or just find out. There are 2 or 3 slots on each piece so just go around and carefully insert them. All in all worth buying.

It's meant to be thin and foldable, but it can be assumed it's intended for storage rather than assembly and use. I tried 5 sides and gave up after reassembling the other sides about 6 times each. I was thinking of gluing or gluing it, but I have flexible cutting boards that would be much better. I thought about using it as a template for another material like wood, but why pay for it? I would rather return it and buy a thicker plastic or wood. Not worth the money.
