Hazardous high quality Cufflinks in Hallmarked Sterling Silver

Cufflinks based on hazard symbols.
While the properties they warn of are rather unpleasant, the symbols are attractive abstract designs.
The ones I have used are (from the left in image 1) : Radiation, Biohazard and Chemical Weapons.

The symbol is 16mm across and attached to a chain and bar .

Handmade in sterling silver high quality and hallmarked by Edinburgh Assay Office.
