JUVITUS Empty Blank Purple Aluminum and Glass Nasal Inhalers - Refillable Essential Oil Aromatherapy Inhaler for Stress Relief, Meditation & Travel

This is a well-made metal inhaler. The internal reservoir is glass and removable. It fits in very snugly so I don't think you run the risk of it getting too loose upon repeated removal. It comes with one wick, which also fits snugly into the glass reservoir. The only problem I see with this is that it might be a little tough to remove the wick if you want to change it out for another essential oil. The top of the inhaler is flat (not round or mounded), so it doesn't fit in the nose quite like a typical plastic one, but it has several well-placed holes where the essential oil can be sniffed. Overall, I think this is definitely a quality product.
