Seriously?
This is created in the style of the Apple Watch Studio, where you can “build” your perfect Apple Watch case and band combination, and then purchase it straight from Apple.
What is different here is that while the Apple Watch Studio is necessary if you do not want the default case and band combos Apple provides on its Watch page, every option in the iPhone 12 Studio, with the exception of the iPhone 12 itself, is an add-on or an optional purchase. You need to choose an Apple Watch band to go along with your Watch purchase, as they are sold as a bundle. But you do not have to buy Apple’s first party cases, and definitely not Apple’s MagSafe wallet, which is widely ridiculed since its introduction.
Is the iPhone 12 Studio necessary? Definitely not. But rather than purchasing your chosen combination of iPhone 12+case+MagSafe Wallet outright, the options to export your ideal combination to someone else may be the hint they need from you to get you your early Christmas present.
