This is way more heavy than it looks.

Tested these several ways. They are accurate! Do their job perfectly! Not a bad price either.

This is for my Grand kids ages 8 and 5&1/2. They are both interested in science. This will help them with the metric system of weights. They are very cool. By the way the weights are slotted so they wont fall off the hanger. There is a slot at the top near the hook where weights are added or removed, I like that. They will go very nicely with the spring scale that I have.

I ordered this for my sons science kit for school. It arrived in good shape and works fine.

Just what my lab needed. Fits the thicker-necked mass hangers.
