Well, there may be some, but I find them to be a handy dandy tool to have on hand and they make great gifts! Ours flasks are handmade and each one is uniquely designed. They hold 6 oz of your favorite brew and they come in a black velveteen pouch. These are in limited quantities so if you like one you had better order it right away. They can be found at Soul of the Rose in the Interesting Accessories page.
