Why we build in sets
A case is the object you touch most and look at least.
Most people end up with a black case, a beige strap bought six months later, and a clear AirPods cover that was never meant to sit next to either of them. Nothing is wrong with any single piece. Together they look accidental.
So we design the whole set at once. Same colour, same finish, same edge radius, approved as one proof rather than five. It takes longer at our end and it means fewer options at yours — but what you carry ends up looking like a decision instead of a pile of purchases.
