Review on Culinaire Bottles Stainless Droppers Included by Christina Stanley

Nice and good size. But very thin. Fragile. I was having a break today when it slipped out of my hand and fell onto the counter from a height of 6 or 7 inches. Also, I went back and re-read the specs on how to install the rollerball. I forgot that the lid has to be tightly screwed on for the ball to work properly. These instructions were not included with the bottles, but should have been in my opinion. After adding oil and carrier oil and firmly attaching the top of the roller, I couldn't get the ball to roll. It was uncomfortable. My fault for not remembering, but it would be helpful if that information came with the bottles.
