The plastic used in the Flight Stands is a bit thicker than the materials used in the invisible counters set. The fit of the pieces in my set was so tight, I didn't need to glue them. I was originally rating the product @ 4 stars with only two in the kit. Upon closer inspection and assembly, I realized that each one consists of 5 separate parts. The result is a solid alternative to using the upside down clear dice box!
