What’s in each Mystery Box?

We can’t spill all the secrets- but here’s what we can say! Each Mystery Box is curated around a fun theme and comes with subtle hints to help you pick the perfect one (or more!). While the contents are a surprise, you might unbox: fan- favorite styles, never-before-launched exclusives styles, or your new fall staples!

What happens after I place my order?

Great question! As soon as your order is in our system, our small but mighty team will spring into action. We’ll conduct all the necessary checks before packing your items up with care. Our packing pros (human, but still pretty speedy) will do everything they can to get your order out quickly. That said, delays do happen from time to time. Our shipping carriers may also experience delays in scanning labels due to volume, so we appreciate your patience as they work to get your items to you.
