I purchased this a while ago and used it once, then stored it at home. I am decluttering, so I will be listing this item until November 24th. Folded: Approximately 31 x 20 cm Unfolded: Approximately 31 x 76 cm There are no noticeable stains, but please understand that this item has been stored at home for a long time and has been used once. Thank you for your understanding.
