These are a Christmas gift that we have had an eye on for several years. The engineering behind these is stunning. We have shopped with Grand illusions many many times. Amazing quality. Customer services. Just fantastic. Can’t praise them enough. So excited when the emails come with clever gizmos and gadgets and brilliantly clever videos to watch.

Purchased these for my mathematician father as a gift. He loved them! Very well made and heavy, and great size.

I've always wanted a set of these after seeing a similar effect on Mr Wizards World as a kid.

The solids are very sturdy and also much larger than what I expected! Very very positive experience. However, there is one thing that I wish was included, and that's a container. You open the box, and there's pretty much another box inside yet another box, but you finally get to the solids and they're wrapped in paper! No box, not even a bag! I don't know if it's just me carrying to high of an expectation, but I do think that something to carry them in would have been quite a nice touch. Overall.
