The Unboxing Moment

You open your weekly D-Nest package—a beautiful, doll-like set of 3 nested boxes made from pressed birch wood. As you unwrap each layer, the companion app pings: "Based on your 12 hours of beach time last week, you only need 1000 IU today." You pull the exact number of capsules from the innermost chamber, realizing your smart bikini actually KNOWS your body better than you do.
