Tiffany & Co. 2 piece china cup set was inspired by the paper cups used to serve drinks in the Tiffany stores worldwide. These 10 oz cups are suitable for either coffee or tea. Fine bone china made in Japan. 100% Authentic with packing slip description included from Tiffany. Makes a lovely shower gift, housewarming and special occasions. Condition: NEW and never used. Comes with original box, ribbon and packing slip with personal shipping information removed. NOTE: As of late in 2022, Tiffany no longer provides numbers on the bottom of the bone china paper cup set. I personally called customer service to find out why these are different than earlier versions of the china paper cup and was told this by the customer agent. If you have any more questions regarding this feature just mentioned, please contact Tiffany.com to verify this information. Ships Same / Next Day Pet and Smoke-free Environment
