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.
