I picked up these new bottles from my supplier thinking they'd be perfect for the fragrance concentrates. Admitedly I thought they might be a little bit bigger than the plastic droppers, but I didn't realize by how much. They seem to hold up very well against leaking and I've been mailing pepper nutmeg back and forth now without issue.

They hold much more than 3 mL though so please be aware when you get them. 3 mL is about 1/4 full. If you'd like more than a single serving of a particular fragrance concentrate it will come in the same bottle up to 12 mL.

Just thought you'd like to be aware
