"In Search Of" on Poshmark....

Hello!! I currently have a set of these lovely "Keira Palampore Multi" Pottery Barn bath towels, but they're a few years old now, and looking a bit seedy. I am desperate to find one or more partial or complete sets of these, since my entire guest bathroom is decorated around these towels. Many thanks for any help you other Poshers can provide--eternally appreciated!! :-)
