Great for making your own oil combinations!
These are nice little bottles to use with essential oils/carrier oils but they do tend to get a little greasy on the outside.  I'm not sure if they actually leak or if it's just residue from spraying. The tube was SUPER long and we ended up cutting it because it wouldn't stay down far enough to use almost half of the bottle.  Not a big deal, just fyi.
