Not cheap
These are not the dollar tree glasses! They are far more sturdy than I expected. They are attractive, very clear, well made. I will buy these again after I loose these!

Surprising quality for the price
Love this company. Quality better than expected for the price. Originally ordered from Sigvan several years ago - the glasses are still going strong. I ordered again just for more colors. Comfortable, strong but light weight. Before finding Sigvan, I wasted a lot money replacing readers that didn't hold up.
