Oud vibrations
I personally add a drop of NGS and shake to "deglaze" the vial and make a sort-of eau de parfum, but I understand that some may object to the use of alcohol. I imagine a light oil like grapeseed would work too. I also keep them just to smell for reference, even though there isn't any left to apply to the skin.
Any other tips for empty vials?
