Vintage Ehrlich Rose Metal Hair Wavers Set of Four Made in 。Set of 2 hard to find marked hair wave \"waver\" clips used in the 1920s - 40s to make the flapper style waves so popular in that era. These have a patent number on them and were patented in 1929 under the name of Rose Ehrlich. This listing is for one pair, I have 3 pair total available as of posting this listing. Size: approx 6.25\" l x 1.5\" w, the arc is about 5\" h Condition: Excellent vintage condition, the clasps and hinges work well. There is some corrosion/rust, mainly on the back side of the hinge but they have been cleaned and the majority of the metal is smooth & clean. Have you found your thing of beauty?
