A4サイズ1枚を折り紙のように組み立て使用するの紙製の急須。急須で淹れるお茶は、湯を注ぐ際の対流により葉が開き、茶葉本来の味や香りを余すことなく抽出できる。価値観や生活環境の変化により急須を持たない家庭が増える中で、正しく淹れた本当に美味しいお茶を誰もが手軽に試すことができる、体験型のギフト商品として企画された。
軽く、かさばらず、割れないため気軽に持ち運ぶことができ、アウトドアでも使用が可能。牛乳パックと同じ防水性に優れた「ミルクカートン紙」を使用し、お湯が漏れ出ず、三煎程度を安心して淹れることができる。

This paper kyusu is made by folding an A4-size sheet of paper like origami. When tea is brewed in a kyusu, the leaves open up due to convection currents when the water is poured, allowing the original flavor and aroma of the tea leaves to be fully extracted. As the number of households without kyusu teapots increases due to changes in values and living environments, this product was designed as a hands-on gift that makes it easy for anyone to try a properly brewed, truly delicious cup of tea.
Lightweight, bulky, and unbreakable, the kyusu can be carried easily and used outdoors. It uses the same waterproof “milk carton paper” as milk cartons, which prevents hot water from leaking out and makes it possible to brew about three cups of tea without worry.
