This is a set of two original yoga blocks from the YouTube yoga channel B-Flow (formerly B-Life). I opened them with the intention of using them after purchase, but they have been stored unused. They are new and unused, but there was a black mark on them from the beginning. Please check the 5th photo. Please consider purchasing only if you understand the above and that they are stored at home.
