What is your return policy?
What is your return policy?
All sales are final and we do not offer monetary refunds on any brand — many of our pieces are one-of-a-kind or very small production. At our discretion we may offer store credit on file, or a one-time exchange (fees may apply). What we can offer, and any fees, depend on the brand, on whether the item is custom or made-to-order, and on any lens customizations — prescription lenses, tints and coatings are made specifically for you, so they are custom and generally non-returnable. To be considered, contact us within 3 days of delivery for shipped orders, or 3 days of purchase in store; items must be unworn and in original condition with the original case and packaging. Store credit never expires; once a store credit has been used, that purchase is final.
Can I try these on virtually before I buy?
Can I try these on virtually before I buy?
