Apply textures and polish or mattify

Once you have received your plain rings, it is time for the main event: hammering. Use the hammer and texturing mandrel provided to texturize your plain rings.

After applying the hammered textures, you may choose to polish your rings with the polisher or mattify with the midget buff. The processes from hammering to applying finishes take around 30 minutes. We have prepared instruction videos to guide you along your DIY process.

The lower tier contains the hammer, texturing mandrel, ring sizer mandrel, and tools used to polish or mattify your rings.


We have prepared a detailed instructional video covering every jewelry-making step to support you throughout. If you have any questions or concerns, please feel free to talk to our craftsmen online via Zoom for help.

Fondness Grew with Every Hit


The charm of this course is getting to make your very own wedding bands of high quality at your convenience. The hammered texture is the vital element in creating originality, as the textures turn out very different in different person's hands. Pouring feelings and effort into every hit of the hammer makes your fondness for your ring grow. You may decide if you want a polish finish, a matte finish, or a mixture of both!

Out of all ring widths tried on by our customers at MITUBACI, 2.5mm width appears to be the most universal and compatible with all ages and gender. Larger ring sizes (size 21 to 30) are considered special orders and will incur an additional cost of 10%. Please consult with our artisans for more information.



MITUBACI jewelry-making kit is put together as an effort to produce zero waste. Everything besides the delivery slip is reusable: with a trunk that could be used repeatedly and also functions as the main packaging, and digitizing instruction manuals and warranty cards. For the sake of our planet home and future generations, we strive to conserve our planet's precious resources and seek better ways to protect our home.
