BoxyCharm is a monthly subscription service that delivers a curated selection of beauty products directly to subscribers' doors. Each box typically contains four to five full-sized items, including makeup, skincare, and beauty tools, from both well-known and emerging brands. Subscribers pay a flat fee each month and can customize their boxes to some extent, choosing from various options. BoxyCharm aims to provide value by offering products worth significantly more than the subscription cost, making it popular among beauty enthusiasts looking to discover new items without breaking the bank.
