If you'd like to do an exchange via courier, we can arrange delivery of the replacement item for S$4.50.  Please mail the item you'd like to return to us (at your own cost) and let us have the tracking number. Once we have received the items, we will send the replacement item out via courier. We suggest you use a trackable courier as we are not responsible for any parcels that go missing. Please contact us ahead of time so we can set aside the item in the size you're looking for as there could be a delay in delivery before we receive your returned item.
