Is there anywhere that I can learn more about Mystery Box and the fine print?

Of course, we’ve got all the information you need in our Help Center. You can find all Mystery Box and many other US related matters by navigating to the Help Center via the website footer. 

Plus full terms and conditions to satisfy your curiosity! You can review them at https://www.universalstandard.com/pages/mb2025-terms. We wouldn’t want the suspense to be too much, here’s a quick summary of the terms for you.

Offer is valid until April 30, 2025 at 11:59 pm PT, or while supplies last, whichever is sooner. Please allow up to 4 weeks for shipping. Mystery Boxes are FINAL SALE and not eligible for return, size/color exchanges or Fit Liberty exchanges. Full terms and conditions apply.

Are Mystery Boxes final sale?

Because Mystery Box is such a unique offering and a customer favorite (at an amazing value!), we’re not able to accommodate any returns or exchanges. All Mystery Box purchases are final sale. Trust US with your box!

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 (including an item you might not even realize you need, but we all need a little support) and maybe even a pair of our best-selling underwear. Remember, each box has a curated theme!

It’s a mystery, but one thing’s for sure- you can’t go wrong!

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 team of elves (okay, maybe not actual elves) 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 their magic to get your items to you.

Any questions?
We got you.
