Please be aware that counterfeit products of HIALO AID without lot numbers have recently been circulating... Also, it seems that HIALO AID purchased from the official website from around mid-April of this year has a lot number starting with "K" on the bottom left of the back of the box. We recommend trying the new product. Brand new, unused. A copy of the HIALO AID usage instructions will be included. If you do not need it, please comment on the transaction screen. Instant purchase OK. No price reduction requests, please. We will ship via anonymous delivery. Because it is difficult to fit in an envelope... we will fold the short side of the HIALO AID box by about 1cm. The product itself will not be folded, but please refrain from purchasing if you are concerned. Depending on sales on other sites, we may ship a product with a different lot number than the one in the photo, but we will ship HIALO AID that arrived at the same time or later than the lot in the photo, so please rest assured. Although it has just arrived, it has been stored at home, so we ask for your understanding. Thank you for viewing.
