Vintage 1 Gross -144 -RED Glass SWIRL 18mm Buttons -WHOLESALE

They are bright red, made of glass with a very satisfying swirl pattern on the surface, measure 18mm in diameter and have an integral glass shank at the back.

The intensity of the red varies a bit and occasionally there is a completely different button altogether...

There is also the odd broken one. 

These boxes were found in an old haberdashery warehouse clearance..
