Review title is Not bad. [SEP] I like these bottles, they're a nice size for my homemade products that I see online, however, there seems to be something loose in the pump that makes a strange nice whenever I shake them.  All but one seem to have this issue.  I didn't notice this until after I through the box away, otherwise I would have returned them.  Not sure if this was just a bad batch, but thought I should mention it.
