Only time will tell if they are more durable due to the thick glass. They are by no means accurate. Each bottle has a deformed inner wall. It looks like a small…

I was very pleased with these colorful glass rollerball pens. There should be 9 bottles of different colors in the set but I only have 6 colors. As the packaging needs to be opened, I put the roller bottles in my own plastic bags as shown in the photo. I emailed the seller about the problem. Unlike most sellers, they insisted that I send them a photo to prove I was honest. I did just that, only to get an email asking if I was sure it was their product at all. When I persuaded them, they told me
