This is a convenient scale to have when traveling by plane. You can especially use it to check if your luggage is within the 7kg limit on your return flight, so you don't have to worry about excess baggage fees! The main unit is small, weighing about 50g, making it easy to carry around. To use it, turn on the power and hang the item you want to weigh. The weight will be displayed. The backlight turns on after the power is turned on and during weight measurement. Batteries can also be purchased at 100-yen shops. Regarding shipping, please understand that the white box might be slightly taller than the size of a mailbox, so the box might be slightly crushed, but the main unit is within the mailbox size, so it's okay. I've taken photos using the one I personally use, but I will send you a brand new one.
