What it shows
Clear glass forms the small cylindrical base so you can see your oil level. The turned wooden lid threads directly onto the top, soaking up drops and diffusing them without metal parts.

We keep these small glass bottles on our side shelf. Each one holds 5 ml and closes with a porous wooden lid that lets scent seep out slowly. The cord knot slides to adjust where it hangs, whether around the neck or over a rear-view mirror.
Sold as a set of 10: the count and any options live on the partner listing.

An adjustable hanging strap threads right through the cap. You slide the knot to change the drop length, which keeps the bottle steady on a peg, mirror post, or worn loose.
The smooth glass walls wipe clean with a cloth when oil runs down the thread. Keep the outer wood dry between refills so the grain stays tight and holds the seal.
