Yes to this ^^^^^^^^. There are *some* glass bottles out there with eye dropper caps that leak HORRIBLY and have been a nightmare for other vendors, leaking in the mail, having to replace full orders for their customers, etc. I'm sure you will do your research on that and save yourself a big headache! I'm game with either plastic OR glass. I've saved all my old bottles and anyone who hasn't can start doing so now, or buy a few. They really are inexpensive and I don't like to shake and open a big bottle every time I fill a
tank unless I am sure it is going to go really fast - lets in too much air and light, etc.
Pretties are good!
