Official Sport Stacking Set, Blue - 12 Cups and Holding stem | Top Grade Materials, Low Friction | WSSA Approved

These Speed Stacks are fantastic for building hand-eye coordination! My kids love the challenge, and the quality is durable enough for daily practice. A fun, active way to keep them entertained.

Fun for my kids! Learned with my kids on how to speed stack and it's very addictive. Reminds of the early 2000s.

I tried different brand. This is the only one with hard plastic so that you can easily grab the cup without worrying about break it. Other brands are too soft. When you grab your cup fast, you will worry about breaking them. I will recommend this product

Kids love, good quality

I got the cool blue speed stack cups for my daughter because she is really into cup stacking. These cups are amazing but our family had trouble scanning the code. I love how the black thing hooks on to the cups! But it took my daughter time to figure it out. They have great sturdiness and durability. Speed Stack cups are great quality too. I wasn’t sure about them because I kind of thought the price is a tiny bit high but once I saw my daughter playing I knew they were worth the price. Speed Stacking Rules!!

This was a BIG hit for my 8 year old grandsons bday.

These were a gift and I have it on authority they work well.

I like the thing that holds them together when carrying them! I use them to teach my grandkids how to do cup stacking! Cup stacking develops concentration, focus, and reading skills! Plus you become the coolest kid on the block when you get good at it!

Très bonne qualité

Satisfecho con la calidad del producto

Como parte de un ejercicio de neuroplasticidad me recomendaron comprar esto, la verdad es muy divertido.

As expected. My son has been making so much of his joy know with the noise of the stacking !

These are fantastic, grandson has autism but handles them great,
