🚨 NOTE: Small lots (not singles) may ship in eBay-branded multi-slot cards envelopes, sans holder/s. After a year of use with no issues, these have proven to be a safe way to ship small lots, avoiding having the charge for Ground Advantage, while also meeting the USPS requirements for eBay Standard shipping. Semi-rigid holders may also be used for this same reason.
Summary - Cards will be as protected as possible while still following USPS rules and attempting to avoid excess charges and/or returns.
