An onigiri mold packs cooked rice into a neat triangle so you can add a filling and wrap it in nori. Most are plastic, some are stainless steel, and a few are wooden. Shape, depth and how easily the rice releases vary from model to model.
The six molds below include a three-piece plastic kit, a stainless steel mold, two molds the sellers describe as made in Japan, a hinoki wood tray and a six-cavity storage mold. Sizes and materials come from each listing page. We have not used these molds ourselves. Origin and material claims are the sellers’ own.

Onigiri Mold FAQ
Do I need a mold for onigiri?
No. Many people shape rice by hand. A mold makes the shape more even.
Can I use these for musubi?
Some kits include a musubi press. Triangle molds alone are meant for triangle rice balls.

For a first kit, the TAORISH. For steel, the choxila. For a light mold, the JapanBargain. For three at once, the TIKUSAN tray. For wood, the TIKUSAN hinoki. For six cavities, the MXYEVL.
