Pyramid Spiral Cone Toy (Big Version 4.92x2.76) - Reversible Passthrough Sculpture for Calmness & Relaxation - Impossible 3D Printed Optical Illusion Gadget, Fidget Desk Toy for Kids & Adults

Great! My son loves it.

I picked up a handful of these for stocking stuffers. My kids love these things and I've got one for my desk as well. They're very cool. I'm not going to say you'll sit for hours on end playing with them, but I do mess around with it a few times a week for a couple passthroughs. The ingenuity behind them is impressive. As far a neat gadgets go, these are right up there.

The media could not be loaded.

At nearly 5" tall, this was larger than I realized, but that also makes it interesting. It works just as it should, sliding through from any direction. These are fun toys, and I enjoy the design. The green and white is not as flashy as other color options, and I've learned I like the ones with a built-in shininess to them. These are quite loud however, the sound of the materials as it slides through it not quiet at all. This printing works very well and seems sturdy and of good quality.

I first accidentally ended up with one of these that was only 2.5” tall. When I realized my mistake, I ordered this one. I was excited to get it in and it was definitely a bigger size and better suited for adults/teens, but it wasn’t working well at least. I realized it had someone sticking to the bottom of it, I’m assuming from the printing process. Once I was able to get it all off, it worked much better. It functions how I thought it would and is cool to look at. However, the biggest issue is how loud it is. With the sound, you could really only use this when you’re by yourself. It definitely could not be used in a classroom or while doing homework next to your siblings at the kitchen table. My 11yr old niece actually preferred the smaller size of these that I have because the sound on this one was too loud. So while it moves the way I expected it to, the sound made it more distracting than it should be. Hopefully it’ll get quieter over time with use.

I got this Pyramid Spiral Cone Toy as a gift for my kids' cousins, and it was a hit! The optical illusion is so mesmerizing—it kept everyone’s attention for quite a while. The cousins loved the tactile feel of the spiral design and enjoyed playing with the reversible parts. It's sturdy and perfect for curious little hands.It’s a unique toy that also sparks conversations because of its cool design. Definitely a great choice for a fun and interactive gift that stands out!

This has been a great fidget toy for my 5 year old son. It can entertain him for a while which is good for a kid with high energy. One thing that I am not a huge fan of is the loud sound it makes when the plastic slides against each other.

My son has been using this Pyramid Spiral Cone Fidget Toy and it's definitely captivated his attention.He has a collection of smaller cone fidgets, but this one stands out due to its impressive size.While its size is a draw for him, it might be a consideration for others.Overall this makes a great conversation starter and a unique gift for those who enjoy puzzles and optical illusions. I think it's a great gift idea for that someone special.
