Dish Soap — Clear Glass Bottle with Brass Pump (500 ml)

Clear glass is the practical choice here: you see exactly how much is left, which is the one thing an opaque refill bottle never tells you. The pump is brass rather than plastic.

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.
