Bought these glasses 15-20 years ago and being a bit clumsy, broke a few.  Could not find a vendor for many many years, then got lucky and found wayfair.  two thumbs up! 
I tried the little girlie glasses that most supplies foist onto people; now with my new supply I can rest easy.  
I use these he-man glasses 24x7x365 and keep 3 in the freezer for my use.  These glasses are right sized for my needs and rate 5 stars (out of five) easily.
I can't say enough good about them.  THANKS WAYFAIR!!!  and a very big thanks to Libbey!!!
