Loetz wannabe?

This is the third (and hopefully last) item I am going to post today in the "we have never known what this" is category. I'm beginning to get a complex. My husband collects everything! There is nothing he doesn't like. He stops in peoples driveways and picks through their rocks! You think I'm kidding? Anywho - I was with him years ago at the auction of an art glass lover and he believed these to be Loetz. His tags are still on the bottom. They have set on a shelf ever since. I really doubt they are Loetz - mainly because the top edges are flat - almost a sawn off look - really unfinished looking. Doesn't seem to me like something Loetz would do? Anyway I'm in a discovery mood and I just thought maybe somebody could help identify? Again, I have scoured the internet and havn't seen anything quite like these so I give in. I really hope someone knows the answer to this one?
