I bought these at a thrift store. $4 for all 3.
I think they look really old. But i/m not very good with items like this.
height 5 1/4, 4 1/2, 3,1/2 inches
The wood stopper is 2 1/2 inches
Unfortunately two of the stoppers were missing. Went back several times but with no luck.
Any information will be appreciated.

Thank you,
