Please note that there may be slight variations due to amateur measurements and home weighing. Please check the images. I looked for the certificate of authenticity, but I couldn't find it. Please examine the images carefully, and only purchase if you are satisfied. As this is a branded item, the buyer is responsible for the final determination of authenticity. Due to the risk of product substitution, returns are not accepted under any circumstances. I think the price is quite low since I don't use it. Instant purchase is OK.
