Received in October 2025. Hyaluronic acid supplement for joint support Sheet-type hyaluronic acid patches for direct application to the knee 6 patches x 2 bags Approximately 6.6mg of hyaluronic acid per patch Hyalo-Aid Knee Support (1 piece) Brand new, unused. Immediate purchase OK. Please be aware that counterfeit products without lot numbers have recently appeared. Shipped via anonymous delivery. As it's difficult to fit in an envelope, I will fold the short side of the Hyalo-Aid bag by about 1cm. The product itself will not be folded, but please refrain from purchasing if you are overly concerned. I am also using this product, and I have a lot of it, so I am selling some. I will include a copy of the Hyalo-Aid usage instructions. If you don't need it, please comment on the transaction screen. Since Hyalo-Aid tends to peel off easily, I wear this support at night. Would you like to try it? Depending on sales on other sites, I may send a product with a different lot number than the one in the photo, but I will send Hyalo-Aid that arrived around the same time or later than the photo, so please rest assured. Please understand that this is a home-stored item. I am also selling on other sites, so please be aware that I may delete the listing suddenly.
