This is a 1960s modernist amber glass cube candle holder designed by Rudolf Jurnikl for Sklo Union of Czechoslovakia. It measures 2 3/4 by 2 3/4 by 2 3/4. It is in very good condition with no chips, cracks or pronounced wear - I did feel a fleabite on the underside edge, but this is not visible and really nothing. This particular piece is seen in clear but appears to be much less common in this amber colour. Great piece for a modern decor!
