Received in September 2025. Hyaluronic acid supplement for joint support Sheet-type hyaluronic acid patches for direct application to the knee 6 patches per pack ✖️ 2 packs Approximately 6.6mg of hyaluronic acid per patch Hyalo-Aid Knee Support (1 piece) New and unused. Instant purchase OK. Please be aware that counterfeit products without lot numbers have recently appeared. Shipped via anonymous delivery. If it's difficult to fit in the envelope, I will fold the short side of the Hyalo-Aid by about 1cm. The product itself will not be folded, but please refrain from purchasing if you are concerned. I am also using this product, but 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 as the photo or later, 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.
