Match the refill to the exact reference
A refillable bottle requires a refill suited to its fragrance, concentration and sometimes its size. Do not infer compatibility simply because a spray pump can be removed. Consult the manufacturer’s instructions: some systems can be filled at home, whereas others require a visit to a boutique equipped to provide the service.
Keep an object you actually use
Refilling makes practical sense when you want to keep wearing the same fragrance and reuse its bottle. Compare sizes and service conditions, then follow the handling instructions. Environmental benefits depend on the particular system and how it is used; the word “refillable” on a box does not describe the whole picture.
