I believe these old pressed glass berry bowls are one of the McKee glass 'tec patterns. Toltec? Rotec? Quintec? Yutec? There's about a dozen of the 'tecs, and they all look pretty much the same to me!
These are very heavy, with a nearcut feel to them, none are marked with the McK mark - or any other mark - that I could see. They're about 4 3/4" across the rim, in good condition. No noticeable wear or clouding, just a few fleabites over the lot.
