MITUBACI's popular workshop, "Wedding Ring Handcraft Course," can now be experienced in the comfort of your own home. This course allows those who want to make rings at home while relaxing and not worrying about time, or those who have had difficulty coming to our store due to distance, to make authentic hammered wedding rings in a casual manner.


Order a kit and a trunk containing tools and ring samples will be shipped in 5 days.

Measure your ring size with the finger gauge in the trunk and choose your favorite material (Platinum950 or 18kGold).
Scan the QR code provided and fill in the required information. MITUBACI veteran artisans will create a plain finish wedding band accordingly to the details you provided, including engravings (if any). Your rings will be shipped out within 5 days upon order and be delivered to your home.

Once the plain ring arrives at your home, it is time for the main event: hammering. Using the provided hammer to create a pattern on the ring, you will form your own original ring. The ring is then polished to completion. If you wish, matte finish is also available. The process from hammering to finishing takes about 30 minutes. We have prepared a video showing tips for pattern insertion, so you can create with peace of mind.

Now you have a perfectly sized original and handmade wedding band while staying in the comfort of your home!
Please remember to return the tools to MITUBACI using the delivery slip provided within 10 days of receiving your plain rings.
Shipping costs will be borne by MITUBACI.
Customers who order the kit will receive a two-tiered trunk containing all the tools necessary for making hammered rings. The top layer contains a sample ring that you can hold in your hand to check the texture of the finished ring and a ring gauge to determine your finger size, and the bottom layer contains tools such as an imo-hammer and a core bar, all arranged in a functional manner. A sizing stick to measure your ring size is also included.
Instructional videos are available to review each process in detail at any time. If you have any questions or concerns, please contact us anytime by phone or inquiry form.
Choose from 3 colors of metal. Whether it's classic platinum or shades of gold, all metals are of the same base price.
