Quick answer
Choose the M+ Guaiac Wood ATOM.iser Set for a warm, woody signature scent in a complete travel case, or the M+ Iris ATOM.ISER Refill if you already own the ATOM.iser case and prefer a lighter, floral note.
Scent profile: woody warmth vs floral freshness
Guaiac Wood delivers a smoky, resinous woody character that feels grounding and sophisticated. It’s a bold choice for those who want their fragrance to make a statement without being overpowering.
Iris brings a delicate, powdery floral profile with a subtle earthiness. It’s softer and more airy, ideal for everyday wear or for layering with other scents.
What you get: complete set vs refill
The M+ Guaiac Wood ATOM.iser Set is a full travel kit: the durable, anodised metal case with a twist-and-spray mechanism plus the Guaiac Wood fragrance. It’s ready to use right out of the box.
The M+ Iris ATOM.ISER Refill contains only the Iris fragrance and requires the ATOM.iser Travel Set case (sold separately). This makes it a cost-effective refill if you already own the case, but not a standalone purchase.
Trade-offs at a glance

- M+ Iris ATOM.ISER Refill: Refill only with a light floral scent. Requires the ATOM.iser case (sold separately). Lower price ($45.75) but only works with the case you already own. Ideal for existing ATOM.iser owners who want to switch to a fresh, floral fragrance without buying a new case.
- Scent longevity & versatility: Guaiac Wood projects a longer-lasting woody trail; Iris is more subtle and fades closer to the skin. Both are designed for on-the-go touch-ups. Choose Guaiac Wood for lasting impact; choose Iris for a discreet, everyday floral.
