How to store solid perfume
Store solid perfume in its securely closed case under the conditions specified by its maker. A balm or wax-like presentation needs attention to temperature and handling; compact packaging does not make it unaffected by heat.
A HUME Fragrance buying guide

Avoid unsuitable heat exposure
Choose an appropriate storage place instead of leaving the case in direct sun or a parked vehicle. Do not improvise heating or freezing to alter a changed texture.
Follow contact-handling directions
Use the intended applicator or method and keep the case closed between uses. Treat the balm as its specified cosmetic rather than a multipurpose product.
Keep refill details
If the case is refillable, retain compatibility information and use the specified refill. A replacement pan with a similar shape is not automatically supported.
Try this before you buy
Check the case's closure, storage guidance and refill identifier before making it a permanent bag item.
