This article covers the 6-meal trial set (160g x 6 meals) of a 4-variety mix of packed brown rice (“pakku gohan”), 寝かせ玄米 (nekase genmai, “rested” brown rice), sold by the 結わえる 楽天市場店 (Yuwaeru Rakuten Ichiba store) on Rakuten Ichiba. You choose the number of meals from 6, 12, 24 or 48. It is hard to tell how many packs of each of the four varieties (adzuki bean, black rice, 15-grain and mochi-mugi barley) come in the box, how long it keeps and how to heat it. So this article organizes what the product page states and the Rakuten reviews into five points: content volume, storage method and shelf life, ingredient labeling, gift suitability and reviews.
What We Confirmed
- Content volume and the breakdown of the 4 varieties (for the 6-meal trial set)
