Summary: Is This the One for You?
Deciding factor: You want to use it one portion at a time, and keep it in the freezer to use in the ways the shop suggests, such as rice bowls and hand-rolled sushi.

- The Rakuten rating is 4.5/5 (11,249 reviews). Within what we read, the points raised were a fishy smell, bones, sinew or hard bits, and a short best-before date on arrival
