These looked great until I saw the price tag

Something is fishy though, the seller is theresa28bass and has the email address of wdwrksltd@ivoryworksltd.net (also linked with Banyan Bay) which is the email of a now defunct (I believe) site that sold ivory of all types as well as Sambar Stag and other knife handle materials. I know because I bought some very nice mammoth ivory scales on sale, interior, not exterior and pure white, white as I've ever seen.
On the back of the set of scales is the name of a website, Banyan Bay, also an eBay store as well as an independent website. Some how these are all linked together.
On another site that sells a lot of mammoth Ivory, I believe these would go for a ballpark figure of $200.00 and a regular eBay auction, $90 to $130, depending on who is buying that day.
