We can do our best to change your order if it has not been sent out by our warehouse, but we only have a small window to do so. Our warehouse processes your order as efficiently as we can, and we might not have the time to update this change, even if your order has not been marked as shipped at the time of your email.Drop an email to help@thinase.com with your order number and indicate the correct model/colour you want. Our support team will be with you shortly to let you know if your request is successful.
