On the one hand, if you look at the usual curly flash drive. But here Manworksdesign worked hard. Made a waterproof flash drive.

In my opinion it is very convenient, and most importantly, safe for information. Anything can happen. Have you come under heavy rain, drenched you with water, etc.? Information will not be lost. I recently acquired this one myself. Water does not miss.
Finding the use of an underwater flash drive is not so difficult. Especially as a gift to friends - the very “What you need” =)
