I received this from an acquaintance about a year ago. I haven't used it since receiving it. It's in a clean condition with no noticeable stains or damage. The sizes are labeled as L and M. The brand is unknown. Both appear to be the same product, just different sizes, but I'm not sure of the details. To prevent deformation, I will sandwich the items between cardboard or thick paper, take measures to prevent water damage, and ship them in a box. The condition is good, but please understand that these are pre-owned items stored at a private residence, so I appreciate your consideration as a used item.
