Copper Flask For Liquor with Pouring Funnel, 9oz

Regarding some of the negative reviews: This is a REAL COPPER vessel. It should go without saying that nothing should be left in copper vessels for an extended period—even water. Copper will naturally build up, affecting the taste, not to mention the "healthiness" of whatever you're drinking. This is meant to be used to store liquid you will be consuming soon—like the next day or two at most. In this case, it will usually not affect the taste of whatever you're drinking, though you should avoid storing acidic liquids in it, even for a short period of time. Do research on copper vessels before buying to decide if it's right for your planned use. Regarding the item itself: I'm 100% satisfied with this product. It's quality and the right size for carrying a small amount of water (or whatever) wherever you go. It looks fancy too. Would purchase again.
