Vintage Made in Japan Red Glass Web Earrings

As you can see I am listing a lot of glass items in my store lately... brooches with glass cabochons, an amethyst glass stick pin, and these. Don't you think these are cool- these are made in Japan vintage screw back earrings? They look like red spider webs and are really unusual. Unfortunately I couldn't get the lighting right when I took these pictures and they look rather orange colored- in person they are a lovely BLOOD RED...
