Speed Stacks | Official Sport Stacking Set, Lucky Duck - 12 Cups and Holding stem | Top Grade Materials, Low Friction | WSSA Approved

すべてセットになっており満足ですが、ちょっと高いかなと個人的には思いましたが、セット内容は完全で満足です。

Easy and simple to use - who wants to challenge me to Rubik's cube? I can solve faster than anyone!

My order arrived before the projected time. It arrived in a plastic bag with no instructions or any paperwork. One of the cups arrived broken, but still useable.The cups were recommended by my kids PE teacher as a fun activity while everyone has a stay at home order due to the Chinese Wuhan virus.It is great for eye hand coordination, and some of those kids on YouTube are amazing.Very nice product, took off 2 stars due to broken cup and no packaging. Even though a cup arrived broken, still happy with the purchase.

This photo shows many sets of cups. I thought this would be a good deal, the picture is not a picture of what arrived. I stack of cups... I am returning these and purchasing several stacks for the same cost.

Had this for months and still works great.
