I don't quite remember how old my child was when they stopped using it, but I think their feet were already sticking out when they were three and a half. I even tried to attach it to the back seat of a bicycle. There are no instructions. I used to wrap the square cloth on top around the back of the stroller and tie the strings to secure it. It seems warm with a lot of cotton inside, but the shoulders are exposed, so outerwear is necessary. I washed it before listing it. Some fleece is coming out here and there. There is a little dirt on the foot area. Image 11 The side of the metal fitting where the zipper slider on the foot area is inserted is originally cut, but it's slightly frayed. Images 12 and 13 Please understand that there may be other oversights. The colors may look different. It will be shipped in a compressed state. Please refrain from price negotiations. I will ignore comments asking for a price reduction. The following is quoted. I have corrected the awkward Japanese, which appears to have been created using a translation function, to make it sound more natural. - This is a windproof and cold-protection foot muff that gently wraps your baby. - The square cloth on top can be used not only for wind protection but also for securing it to the stroller. - Reflective tape is attached, so you can rest assured even at night. - Easy to install. Simply thread the stroller's belt through the holes and close the zipper. - It can be attached to most strollers and buggies with a 5-point harness. - It transforms into a hood just by pulling the strings. - Cute bear embroidery. - Water-repellent finish for peace of mind on rainy or snowy days. - There is also a zipper on the bottom, so you can remove the foot cover to adjust the temperature. - Made of coral fleece fabric, it feels soft, fluffy, and airy. - The back is non-slip for safety. - When the zipper is fully opened, it becomes a sheet. Additional notes * I feel like it didn't wrap around as much as it claims to "transform into a hood." (There is a rubber stopper on the top of the bear.) * The effectiveness of the reflective tape and water-repellent finish may have diminished.
