The Numbered Line Compared: All Six No. 0–5 Signature Fragrance Oils

The Numbered Line — No. 0 through No. 5 — is Sunsum®’s core fragrance collection. Together, the six oils form a complete fragrance wardrobe: one for every room, every time of day, every mood state. Individually, each is a distinct proposition with a specific character, ideal use time, and target buyer.

Here is every fragrance in the line, compared directly.
