there are two signs of fuguang thermos cups, one is fga and the other is Fuguang.

In fact, both of these logos are from Fu Guang, and Fu Guang is not a single product line. The cups of both logos are produced by Fu Guang Company, and a small part of the product lines of FGA, a wholly-owned sub-brand of its company, will overlap with Fu Guang.

fga and fuguang are only different in production lines, and there is no difference in quality, technology, function and use. You can pour boiling water into a thermos cup, tighten the cork or lid clockwise for 2-3 minutes, and then touch the outer surface of the cup body with your hands. If the cup body is obviously warm, it means that the product has lost its vacuum degree and cannot achieve good thermal insulation effect.
