We use this to keep our two pet rats in when we are cleaning out their cage. It is shorter than a shoe box but slightly taller, so is good for short periods but doesn't give the animal any 'running around' space. This plastic is quite robust on the base, although the clear plastic lid feels a little more brittle and thinner. it comes with two carrying handles, which raise up from the ends like a supermarket shopping basket.
The plastic lid hinges up at one side and you place your pet in through the top, the sides are quite steep, so you can then get the lid down before your pet jumps out! The only slight problem is the opening and closing catch on the lid, which is a small oval shaped button, which you have to press in, so releasing it from the oval hole which fixes it in place. getting it closed is a bit fiddly and you have to make sure it is snapped in place correctly.
However, for the price this is an excellent product and our rats seem happy enough in it!
