An amber glass bottle with a matte black steel pourer, made to hold cooking oil.
Oil goes rancid in the light, and amber glass is the cheapest honest defence against that. The steel spout pours a thread rather than a splash.
Les Flacons de l'Apothicaire assembles its bottles in France and labels them by hand, with a waterproof matte label that survives a wet sink.
Fill it from a bulk refill rather than buying a new plastic bottle. The label is washable, so it can be wiped down as often as the bottle is.
