These were great for balloon powered cars the small wheels were almost too small but the kids had fun using them. Would buy again

Good inexpensive disks but dimensions are imprecise
Advertized as wheels but they are flat disks, no rounded edges (ok for my purpose). Product size on Amazon is given as 1 1/4 x 1/4 inch, 3/4 x 1/4 inch. However on the package it is given as ~ 1 1/4 x 3/16, 3/4 x 3/16. That was a disappointment, diameter is correct but I needed 1/4 = 0.250 thickness. I measured the thickness on the large and small disk, both were 0.195. In the Amazon picture it shows a middle layer that looks like wood or glue, but the 2 disks are really 2-ply plywood with a middle layer that is super thin = hardly visible. So they are smooth and look much better than shown on the Amazon page. The small center hole is between 3/32 (0.093) and 1/8 (0.125) inch.
