The most important thing to remember is that it must be escape-proof. Snails are extremely strong (they can lift 10-50 times their own weight!) for their size and could lift a lid that isn't clipped or weighted down. Wooden or cardboard containers are not suitable, they will rot and in the case of cardboard, the snails will actually eat it.

Plastic Storage Container

Available in all shapes and sizes from most supermarkets, DIY stores etc. Very cheap at around £2-10 and easy to clean. Shop around for the most transparent you can find. Some are more cloudy than others, even within the same product range. If you find one that is suitable it's worth comparing it with others next to it, there just may be a more transparent one there.

Holes need to be drilled in the top and/or round the top of the sides for ventilation. Due to the cost and the material they're made from a number of interesting things can be done to these (see here). The top may need to be secured if it doesn't snap shut.

It's usually worth having a few of these around for general snail care, they are cheap, can be used to store peat and they make good emergency tanks.

Спасибо! Значит можно матовый пластик. Классно!

The snails need light so an opaque box is out of the question but a translucent/nearly transparent container will be fine from the snails point of view.

Shop around for the most transparent you can find.

Так, а в чем разница между матовым и полупрозрачным?

в том, что матовое - понятие растяжимое.
"Светопропускание "матового" стекла может находиться в пределах от 10% (т.е. быть практически "глухим") до 80% (полупрозрачным)."
