**Do to ongoing supplier chain issues, the look and size of vials may vary. They will always be at least 2.5ml and in the event we have to substitute them out, they may go up to 3ml. We will not charge more for the larger sizes. **
All oil vials come in the SMAT format in heavy duty glass vials, (with no sprayer). If you would like a different intensity, please let us know in the notes section in the shopping cart.
