I used BF jars for about a year or so. They worked well except for the fact that the lids kept "locking" onto the jars.
Once I used pliers to try to unscrew the lid and actually crushed the jar (under the lid) and pushed the glass into my hand...so be careful.
I also tried test tubes with rubber stoppers and was greatly disappointed. IMO if you get some with screw on lids you'd be better off.
Now I just reuse the vials.
