I bid on and payed $55.00 for what was advertised as a genuine IKEA Tassa stuffed dog from Ebay seller brittafelder (firstname.lastname@example.org) to replace one lost by my son. Fortunately I access to an original IKEA Tassa dog to compare it with. The Tassa sold by brittafelder is obviously different, it is much larger than an original Tassa, has different seams, is made from different material and is stuffed with a different kind of stuffing from an original IKEA Tassa. The Tassa brittafelder sold me also has the stub of a tag left in it, obviously cut by scissors, and equally obviously a completely different material material used than the soft cloth used for the IKEA Tassa dog.
This seller has an apparently endless supply of these Tassa for sale, though the model was discontinued almost 2 years ago, she also uses the same picture for each one she puts up for bidding as the photo of the exact Tassa for sale.
I would not recommend anyone do business with this seller.
