I've been curious about this for a while, and finally bought it, but I didn't feel much effect, so I've decided to sell it. [Condition] I've used it for about 2-3 days, but as far as I can see, there are no noticeable scratches or stains, so I'm listing it as "Like New." [Packaging] I will put it back in its original box, wrap it in a plastic bag, and then pack it in either a padded shipping envelope or a dedicated envelope. [Shipping Method] Yuyu Mercari Delivery. I plan to ship it via Yu-packet Post or Mini.
