It's convenient because the onigiri (rice balls) don't get squashed, so you can just throw them in your bag. A cute Hello Kitty design triangular onigiri case, a set of 2, blue and pink. There may be water spots after washing, so please consider this if you are sensitive to such things. I had others, so I only used these a couple of times, just to put wrapped onigiri in them. Stored in a cupboard for about 3 years. Holds adult-sized onigiri. Each side is 10-11cm, and the thickness is about 4-4.5cm for a triangular onigiri. - Color: Blue and Pink - Design: Hello Kitty - Shape: Triangle - Material: Plastic - Quantity: Set of 2 Thank you for looking.
