Seal is not really tight but it is waterproof.
The top just pushes on, and comes off easily, I'm worried that it will get knocked off, going to put a band around it. Seems to be water tight, hasn't leaked in testing it, just that it doesn't fit as tight as I thought it would. It's long enough to hold 2 smaller bars of soap. Shampoo and conditioner bars will fit. The big shower bars of soap will only fit one, or one big one and something smaller. Has a removable tray that keeps the soap up off the bottom, so it can drain a little. It is a hard plastic type, so I imagine it would break if you stepped on it, for instance. In normal packing and carrying, it should hold up fine. Read more
