Welcome to the community @Robbsy,
The only comment to date is the following, that might be helpful.
As for being advertised on Facebook, that can be far from an authoritative reference or safe purchase in the general case, noting FB Marketplace seems closer to the American wild west than to the likes of ebay or amazon or known online vendors. Regardless of the product I would seek out another supply given a choice (no pun intended) in case the purchase goes wrong for whatever reason…
