I purchased this online. Nastent Classic, an anti-snoring device. Right, 135mm, soft, 2 boxes, 14 pieces total. I used two, but they didn't suit me. Please refrain from individual sales or price negotiations. The expiration dates are "March 2028" and October 2025, two different types. Please understand this before purchasing. There may be some minor scratches on the boxes. If you are looking for a perfect item, please refrain from purchasing. Also, wrapping with bubble wrap will exceed 3cm in thickness and will not be eligible for Yu-Packet. Therefore, it will be shipped in a waterproof plastic bag. As a result, there is a possibility of box damage during transportation. In that case, please contact the post office regarding the shipping accident.
