Have you ever wanted a secret compartment that you could carry with you? The FLPSDE is just that. This handy dual-ended waterbottle doubles as a canister for snacks (or valuables). The dual ended bottle has a durable, stainless steel design that's vacuum-sealed to keep your liquids at whatever temperature you desire. Store up to 20 oz of water, coffee, hot chocolate, booze, what-have-you, and flip it over for a 7oz dry container to stash a chocolate bar for later, or your keys for when you're out and about and don't want to misplace them. It's like being a spy, without the possibility of being the subject of a worldwide manhunt.
