Good for dancers
Color: Lagoon, Style: 2 Blocks
My daughter is an Irish dancer and got these to practice keeping her legs straight. After using for a month we can see a difference. They are sturdy and decent quality. Would give 5 stars but our friends have some that are more comfortable.

Perfect!
Color: Grey, Style: 2 Blocks
Perfect size and very stable and soft. This isn’t cheap and wobbly like some blocks — this is thick and my husband who is 220lbs uses it with no problem! Love it!

Good comfy product, good quality and aesthetic color
Color: Grey, Style: 2 Blocks
First yoga blocks I buy for home. Excellent texture and quality, they are really comfortable for support. The grey color is very aesthetic, I think the shade will be great for hiding any stains or dirt over time. They look expensive and I love that. I tried scratching them with my nails and the marks completely disappeared after a few minutes. The engraved logo is a nice plus. I love that they’re a bit taller than average blocks. The grip is good.

Keeps me cool!
Color: Blue/Grey/Green/Pink
These cooling towels are wonderful. I use them when I play pickleball. I get them really wet and then squeeze out any excess water. When I put one around my neck it is not dripping soaking through my shirt. I can use it to wipe my face and keep me cool. I can always add more water to it as needed. It is soft and the perfect size to wear around my nect.
