We will give a rough estimate of production time for customized products, but as they are handmade, unexpected issues may arise, such as defects that require re-production. This means that the production period is uncertain and may exceed one month, which is normal. In addition, customization is also affected by uncontrollable factors such as the weather. For example, painting the saya cannot be done during the rainy season. Therefore, we ask for your understanding if we cannot complete your order on time, as the delay is necessary to provide you with a perfect product. We recommend purchasing ready-made products whenever possible.
