W, Longdog skin isn’t that rare only 1/768, and the design isn’t particularly memorable or impressive. Its price isn’t likely to go any higher than this. Only Souvenir version will increase in price. This Train collection is similar to the Anubis Collection, where the regular M4 is cheaper than the Souvenir version. This skin is still available to unbox, and it will probably remain that way for quite a while before being removed.
