The Hokkaido-produced “wakeari” (imperfect/irregular, sold at a discount) raw scallop adductor muscle, 1kg, sold by 越前かに職人甲羅組, a shop run by 株式会社伝食 in Tsuruga, Fukui Prefecture, is a frozen product that puts 1kg of adductor muscles with cracks, chips, and uneven sizes together in one pack. It is hard to tell how large the pieces are, by when to eat them after thawing, whether they can be eaten as sashimi, and whether the product works as a gift. In this article, we organized what the Rakuten Ichiba product page and the reviews say into five points: quantity, shelf life, ingredient labeling, suitability as a gift, and reviews. The three features we could confirm on the product page are that it comes in a single 1kg specification, that each piece is individually quick frozen, and that the adductor muscles are described as sashimi-grade.
