If you would like to add something to your order, such as accessories or glue, we can include it as long as the wallpaper has not yet been processed. To ensure this, we recommend informing us as soon as possible by giving us a call. Please note that we are based in the Netherlands and operate in a different time zone, which may affect response times. Once we receive your request, we will send you a payment request for the additional items. After payment, your complete order will be shipped to you.
