THERMOS Model Number: JNS-351 (ESP) 350ml Weight of main body: 180g Lightweight and easy to carry. Since it's something I wanted anyway, I've included an insulated cover. ◆ The main body is in very clean condition. Please check image 4 for details such as heat retention time. The color is dark brown. ◆ Insulated Cover THERMOS My Bottle Pouch with Strap, for 350-400ml, Gray Blue APG-351 GY-BL Comes with a removable shoulder strap. There are some stains and scratches on the bottom, but I think it can still be used sufficiently. Please understand that this is a used item.
