RCI doesn't sell bar glasses on-line. That is something you have to buy on a ship unless you can find someone who has them and is willing to sell them. Please note that you can't solicit for it here. That is not allowed.
All I can suggest is looking at the auction sites like eBay. I just looked and while there are many RCI glasses up for sale, I don't see any like the ones you want. Those glasses are the most popular ones RCI has and they usually sell out quickly on cruises.
