These wonderful heavy glass candle holders are unbranded but I feel that they must have been inspired by designers at the Orrefors Sweden company.
They measure 2.25" across and 2" high.
I did notice 3 small "open bubbles" on the underside of 2 of the pieces (please see last pic) but I believe that these tiny blemishes will be imperceptible when they are in use.
Asking $15.
