Maybe it's been around for a while, and I just missed it. However today I was at the store, picking up those little things you always need, and discovered this little item.
How cool! It's small, will easily fit in a pocket, won't leak and will even pass TSA carry on limits.
Several cruises, I've ended up with a 'raccoon face' (sunburn with white strip where the shades were). This normally results from going topside, or to shore when I didn't feel like or forgot the bottle/can of sunscreen.
No more raccoon face for me, my sunscreen will be in my pocket. Heck I'm even thinking of buying a spare to keep in my camera bag.
