I bought this new about 5 years ago, but I didn't use it much and just kept it in storage, so it's very clean. As you can see in the photos, only the sticker on the back has been peeled off. A soft mat and instruction manual are also included. Operation has been confirmed. I will ship it in this box, sealed with packing tape. Thank you for your understanding. Measure feeding amounts and enjoy childcare ・Calculates the amount of feeding from the difference in the baby's weight before and after feeding. ・Alleviates the mother's anxiety of "I don't know how much breast milk the baby is drinking." ・The feeding amount can be measured in 1g increments, so you can closely monitor the amount of milk intake. ※The feeding amount (difference from the previous weight) is displayed in 1g increments for only 5 seconds after pressing the "feeding amount button". Also great for daily weight measurement ・Measurements in 5g increments to accurately track daily weight changes. ・Weight can be measured in 5g increments up to 8kg, and in 10g increments up to 20kg, so you can use it even as the baby grows.
