I like VONZIPPER and have been collecting them, but I'm selling some to organize my collection because I have too many. This is one of many, so it hasn't been used much and is in good condition. The included bag is dirty and torn, so please consider it an extra. The item was purchased from an authorized retailer, so it is definitely authentic. I am also selling other VONZIPPER sunglasses, so please take a look. If you purchase two or more items, I will give you a 200 yen discount, so please let me know in the comments section. I will change it to a combined listing. Shipping will be by regular mail and will be simply packaged, so please understand. Thank you. Please be sure to read the profile section before purchasing.
