Aennon Essential Oil Bottles – 10 ml. Amber Glass Empty Bottle Set, for The Aroma Nebulizing Diffuser (4-Pack) + 12 Extra Washers Included

The bottles, cap and plastic reducer function fine. The 12 spacers for the diffuser are fine too. But, the cost - well, it was $11.95 for 4 bottles. I thought is was 10 bottles, my mistake, but I could have bought a set of 8 10 ml bottles with caps and reducers for $8 so I feel a little ripped off for the price. Again, the product seems fine - but overpriced.

Good bottles! Work well.
