OS-01 HAIR Glass Bottle

The dropper dispenses exactly the right amount of serum each time, no mess or waste. The glass feels sturdy and weighty in my hand, which makes the whole routine feel a bit more deliberate and pleasant.

Refilling this bottle is a breeze since the dropper pulls up exactly the right amount of serum each time, and the glass feels sturdy enough for daily use on my bathroom shelf. It’s a simple upgrade over the plastic bottle my serum came with, and the dropper tip makes applying it to my scalp way less

The dropper is nicely calibrated, so I get just the right amount of serum without any mess. I bought it as a refill container and the glass feels premium, plus it’s easy to clean between batches.
