MCM vintage crackle glass tumblers, mod pinched shape drinking glasses w/ ruby stain color

Set of six mid century vintage hand blown pinched shape crackle glass tumblers, probably Pilgrim glass or Blenko I think. West Virginia glass, though these have no marks or labels.

The ruby stain color has some wear from use (much more to some than others, see photos). I very seldom find these in the ruby, the crackle glass in the flashed on colors is rare and hard to find - so I was delighted to find a whole set like this!

These are old fashioned glasses, about 3 1/2" tall. Glass has no damage, no chips or roughness at all. Just the wear to the color as shown.
