GoPong's 'Tropic Tan' Sunscreen Flask was designed to look like a regular bottle of sunscreen so you can fill the bottle with your favorite beverage and take it anywhere. Each flask holds 8oz and can easily be filled though its extra wide mouth (small funnel included). Its screw cap provides an air-tight seal to prevent any leaking. Once you are ready to drink, simply unscrew the cap and mix with your favorite beverage. This two Pack includes an 'SPF 15' and an 'SPF 30' so you can sneak two kinds of alcohol around. The flask will pay for itself after one use, so get yours today! Please remember to always obey all local drinking laws.
