I'm actually quite pleased with them
Full disclosure: I only purchased these roller ball bottles because of the promotion that allowed me to get them for $2. That being said, I'm actually quite pleased with them. They are very pretty and uniform is color without a bunch of tiny air bubbles. The screw on caps seem pretty secure so far. The roller balls themselves are plastic though, which to some people may be a problem but not for my purposes. They were shipped securely and arrived in perfect condition.
