ブルーボトル - ヨーロピアンドロッパートップ

The dropper top fits snugly and dispenses exactly one drop at a time, which is perfect for my homemade essential oil blends. The glass feels sturdy enough to reuse for years, and the plastic cap seals tight without any leaks.

The cobalt blue is even richer in person, and the plastic dropper fits snugly so nothing leaks when I tip it. I've been refilling it with my own oil blend for a week now and it still looks brand new.
