Thank you for viewing my product. This product is the baby scale BB-105 with breastfeeding amount function. Please note that this is a different model from the BB-115L released in November 2024, and therefore does not have the "Piyolog" app linkage function or the backlight function. It was manufactured in 2020. I used it with a towel placed on it. I will ship it in the product box. Please understand that the box is not in good condition. It's great for formula because you can see how much they drank, but it was very helpful when I was worried about weight gain and breast milk intake because I couldn't tell with breast milk. Being able to see the numbers makes it easier to figure out how to respond, so it's very useful. Please feel free to ask any questions in the comments. Thank you for your consideration.
