Everyone love these. No one wants to sit on them. It's the Obsidian stone. Perfect pyramid shape. Square bottom. Perfect lines. This thing sits on a clean surface and just beams at you. It's one of those things that you can leave somewhere and forget about it, but every now and then it'll pop into your day and makes things that little bit better. Coolest thing is that every single on is different. Yours will be yours only.
