Helmutite

Helmutite glasses are glasses made of "Helmutite", an alloy created by Helmut. The lenses are tiny, but the design is supposed to make the wearer "look fabulous". Helmut claims they are able to withstand the weight of a Pygmy hippo.

He attempts to sell them to Arthur in "Through the Looking Glasses", but Arthur did not like the design and his mother didn't like the price.
