Gusumin anti-rollover belt. Purchased at the end of March 2024 and used for about 2 months, until mid-May. Improved version with buckle. Home-cleaned. The Velcro area is a little fuzzy and feels slightly weakened, but it still has enough strength to prevent a 7-month-old baby from rolling over while sleeping. Dust and lint were present, but I removed them as much as possible after washing. While using it, there were no instances of spitting up or leaking poop, but there is a slight yellowing at the top, though it's barely noticeable. The box and instruction manual are all included, but to save on shipping costs, I will pack it folded up without the box. If you want the box, it's an additional 500 yen (with a slight dent). I have cleaned it as thoroughly as possible, but there may be oversights as I am not a professional. Please refrain from purchasing if you are sensitive to used items. Thank you. #Gusumin #Anti-rollover belt #Baby #Newborn
