This Is a Three-Tiered essential oil stand specifically for "Do Terra" brand oils though will fit bottles with a 28mm diameter.

Vial stand pictured requires some modification before uploading but is designed to clip on to the side of the stand. (can be mirrored in slicer to attach to opposite side)
