Using these dry bags is a breeze. Just open the magnetic closure, put your items inside, and close it up. The clear TPU window makes it easy to quickly spot what you're looking for. When it comes to the size, pick the one that fits your needs from the various options available.
As for precautions, keep in mind that the bag in the photo is just for color reference, not the actual size. Also, although it has an IPX4 rating, it's not suitable for full - submersion in water.
For maintenance, after use, simply wipe the bag with a dry cloth. Store it in a cool, dry place to keep it in good condition. The silicon - coated 30D Cordura® and PU backing make it durable, but try to avoid sharp objects that could potentially damage it.
