I won this in a FamilyMart Twitter giveaway a few years ago: "Afternoon Tea TEAROOM supervised Shogo Sekine design Original stainless steel bottle winning campaign!" *This is a stainless steel bottle with a strainer for tea leaves. You can easily brew tea by putting tea leaves in the lid and pouring hot water. It's unused, but it has been stored at home. Please purchase only if you understand this. #withstrainer #stainlesssteelthermos
