These work very well for free-flowing samples. They are sturdy, clear and a good size. The concern would be for a thicker lotion - there is no way to squeeze them dry. The other small issue is labeling. I used a 1.2" round label but it puckered a little on the rounded surface. I will play around with that. I got different colors to tell which product it is which is helpful when looking for a specific scent, etc.
