Karashi mentaiko (chili-seasoned pollock roe) is sold under names that vary by shop for its size and shape — kireko (pieces that have broken apart), barako (loose, separated roe), ippon-mono (whole, uncut sacs), and more — so it can be hard to tell from the product name alone how many grams or pieces you will get, or how long it keeps. In this article we organize the publicly available product page information for “Futoppara Mentaiko 700g,” sold by Kanefuku’s official Rakuten Ichiba store, into five points: amount, storage method, ingredient labeling, suitability as a gift, and reviews. Its key features are that it arrives as 2 bags of 350g, and that the gift field on Rakuten shows noshi (gift wrapping label) support and gift wrapping as available.
