Diptyque Cap for Small & Classic Reed Diffusers is a glass stopper inspired by ancient pottery, designed to elegantly pause fragrance diffusion and preserve the scent between uses. Compatible with both 100 ml and 200 ml Diptyque diffuser vessels, it offers a practical and refined way to seal the vessel. It can be cleaned with soap, water, and a non-abrasive sponge when switching between different scents. Refills and diffuser vessels are sold separately.
