No - due to an automatic ordering system, order modifications are no longer possible once your order has been placed online. If your order is still in process and has not been prepared for shipping, we can cancel your order so that you can place a new order at your own convenience with the correct color or size you wish to purchase. Please reach out to info@manduka.com or call our Customer Care Team at 1.877.MANDUKA, M-F 6am to 5pm PST, so that we can assist you further!
