These nautical themed flasks look just like a real porthole. The pocket sized nautical themed flasks are classy and unique. The flasks are the perfect size for sneaking those extra few drinks around; whether it be on the boat, at an event or even while on a leisurely walk somewhere nice.
The nautical themed flasks have been carefully crafted from high quality polished stainless steel. The flask has a machined screw-off top and a viewing window that looks exactly like a real porthole that has been made from durable glass. This unique porthole feature allows you to see exactly how much of your favorite liquor that you have left and when it is time to get it topped up.
