I'm a wildlife biologist and needed something I can keep small fish in while taking photographs. This seemed perfect on paper as it was affordable, crystal clear plastic, had a measurement scale integrated on it for size reference, and large enough to hold the slightly bigger specimens of the general small fish specimens I look for. Unfortunately it was directly shipped from China so delivery took forever, had an unnecessary Chinese symbol on the front of it that wasn't in the advertised pictures, and worse of all, both boxes came cracked / broken.
