ISO Gentle Monster BOLD Siguer MSV1 Sunglasses

Hello everyone, for about a year now I've been looking for the signature piece of the BOLD collection from Gentle Monster, otherwise known as the Siguer "alien glasses." however just finding them is a hassle in itself and on the off chance one does show up on the 3rd party market sites, they're over $500 and sell almost immediately. Really I do not care whether or not they're genuine GM's at this point, I just want that design to wear and I cannot settle for anything similar.
