I am a mosaic artist and like to keep a variety of materials handy. The glass quality was so poor I thought it was some kind of plastic. It appeared to be random glass objects that were smashed and tumbled. It was disappointing because Amazon is my "go to" place(I have your Amazon rewards credit card). I was forced to shop at EBay to get a decent selection of choices.I chose the one star rating because you didn't offer a zero option .
