Usage & Care Guide

1. Water Rinse Tip: Lightly rinse the inside of the mold with cold water before adding rice to ensure the grains release smoothly without sticking.

Frequently Asked Questions

Do I need to wrap the onigiri in nori?
Wrapping your finished rice ball in a strip of nori (dried seaweed) is traditional and helps keep your fingers clean while eating, but it is entirely optional!

What is the difference between the Small (S) and Large (L) sizes?
The Small (S) size makes bite-sized onigiri perfect for kids' bento boxes or party platters, while the Large (L) size creates standard, café-style rice balls that make a satisfying meal addition.

Can I put these molds in the dishwasher?
We recommend hand-washing these plastic molds gently in warm soapy water to preserve their smooth non-stick finish and prevent warping over time.
