Frequently Asked Questions
Everything you need to know about ReliefBox and your menthol stone.
How does the menthol stone work?
Pure crystal menthol creates a fresh, cooling sensation that soothes tension the moment you glide the stone over your skin — a natural, drug-free way to ease everyday headaches and tightness.
How do I use it?
Twist off the wooden cap and gently rub the white menthol stone over your temples, forehead, neck or shoulders in small circles. Use whenever tension builds — up to a few times a day.
Is it natural and drug-free?
Yes. It's made with 100% crystal menthol, eucalyptus, sweet almond and aloe vera oils — no pills, no chemicals, no mess.
How long does one stone last?
With normal use, a single stone lasts several months — it's reusable and economical.
Is it safe to use?
It's for external use only — avoid your eyes and broken skin, and keep out of reach of children. DeepSea is a natural self-care product for cooling, soothing comfort.
