two clear glass candlesticks

Here's a couple old-ish clear (molded?) glass candlesticks, in differing rather plain shapes. I use the term old-ish because I've had them 30yrs or so myself and they were likely "used" when I got 'em (garage sale?) but I don't know exactly how old they are. They both stand a little over 6" tall, on hollow bases a little over 3" square. There are no marks on either one to suggest who made them.

OH -- and about those blue tapers...let's just say that odd things can happen to a boxful of old candles, if inadvertently left out in the bright summer sunshine for a few hours...? ;-) :-)
