These cork yoga bricks are great. They are heavier and sturdier than foam. They look pretty. They are standard size. Very happy with product.

I thought I could sit on it

I purchased this yoga block for my wife and she now has two of them, I have observed their usage a few times, so I can speak from a speculative and unbiased opinion.First off, I must say that the quality of the block is second to none. It has six sides as most blocks do and the corners are beveled adding comfort to griping and holding the block when picking it up and putting it away. Most rectangular blocks have sharp or hard corners making it difficult to pick up from the bottom. Being that this weighs only 1.5 U.S pounds, I must say I don't mind picking up two of them to put them away either.The color, Apple Green as is the case with the one I purchased maybe beguiled me at first as I thought it would have been so green it was edible and produced from apple compost. It is not edible, however, it is made from foam which would also serve a function as a life preserver in most fluids. That is until the human race fills the ocean with plastic and foam, at that point one would need to seek a lower density flotation device than this block to achieve sustained buoyancy.Overall I give it 5 stars because a block with a yoga sounding name, that is an acronym for other some other words that also sound of interest to those who enjoy yoga, and it is a block of foam, quite difficult to foul up that product and it didn't require much packaging. Although it would be amusing to order a block and get a leg roller instead, I ordered a block, received a block, and the block does stand on all 6 sides, which does show it has a predictable center of gravity and doesn't roll or float away.

Llegaron en su empaque e cada uno y muy bien empacado, se ven muy resitentes y de muy buena calidad, excelente producto.

I use the blocks for my on yoga practice. Good material and size exactly like pictures show. Recommend 👌
