Received in October 2025. Sheet-type hyaluronic acid patches for direct application to the knee. 6 sheets x 3 bags Approximately 6.6mg of hyaluronic acid per sheet. Hyalo-Aid Knee Support (one piece included) Recently, Hyalo-Aid received from the official website has a lot number starting with "K" on the bottom left of the back of the bag. We recommend using the new ones. Also, please be aware that counterfeit products without lot numbers are also circulating. Brand new, unused. Instant purchase OK. No price reduction requests, please. Shipped via anonymous delivery. As it's difficult to fit in an envelope, the short side of the Hyalo-Aid will be folded about 1cm. The product itself will not be folded, but please refrain from purchasing if you are concerned about this. Depending on sales on other sites, the product shipped may have a different lot number than the one in the photo, but we will ship Hyalo-Aid received around the same time or later than the one in the photo, so please rest assured. I am also using this product, but I have a lot, so I am selling some. For those who need it, I will include a copy of the Hyalo-Aid usage instructions. Please comment on the transaction screen. 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. Thank you for viewing.
