I purchased this at a store in July 2025 and used it for a few days at work, but the thickness doesn't suit me, so I'm selling it. I think it's in good condition as I only used it for a few days, but I cut off the tag when I started using it. Please understand that this is not a new item. I will pack it in a cardboard box I have on hand when shipping. I'm afraid I can't offer a discount due to shipping costs. Thank you.
