A mystery self-care bundle box is a curated package filled with various self-care items, usually centered around wellness, relaxation, and personal care. Since it’s a “mystery,” the contents are often a surprise, which adds an element of excitement. These boxes typically contain products like 6 oz. handcrafted soap, budget binder and/or body gloss(™), bath salts, exfoliating net cloth, and a few freebies.
