A bug jar with a magnifying glass is a simple and affordable tool for a young researcher who is interested in studying bugs, for example. Of course, you can put anything in the jar that will fit. Rocks, branches, leaves, etc. The jar is easy to take with you, even on a trip.
The Byomic Cup Loupe consists of a transparent plastic jar with a 2x magnifying glass on the lid. The lid also has a separate foldable 3.5x magnifying glass. The bottom of the glass tube has a measuring grid that makes it easier to estimate the size of the object. The grid size is 5mm.
The magnifying glass is recommended for children aged 3–12.
