I received this about six months ago, but I haven't had a chance to use it, so I'm putting it up for sale. 【About the product】 Made of durable stainless steel, so you can use it with peace of mind for a long time. It has heat retention and cold insulation functions, and the body does not get hot even when hot water is poured in. After you no longer use it as a baby bottle, you can simply replace the drinking spout to turn it into a water bottle, making it a bottle that can be used by everyone from babies to adults. ※The top of the box is slightly damaged, but the contents are new and unused.
