This is a Heavy Blue Knot Aprica Koala Ultra Mesh! I purchased it in June 2023. I mainly used it from newborn to about 5 months old. Since my husband and I often took turns carrying the baby, I didn't use the baby carrier very much, so I think it's in good condition. It has been stored in the closet. This is a baby carrier from Aprica, a major baby product company. It's a convenient baby carrier that can be used from newborns to 3 years old, with specifications that can be changed according to the baby's growth and preferences. It is designed to not stress the baby, so I think even first-time moms can use it with peace of mind♡ ↓From the Aprica website The "Koala Ultra Mesh" is a waist belt type baby carrier that can be used in 4 ways from newborns (2.5kg) to 36 months. It was born with the ideal of koala parenting, also known as "Komoriguma" (nursing bear). Aprica's unique three functions solve the problems of baby carriers. The first is the petal-like "petal structure." You put the baby in the carrier after putting it on, so you can quickly carry the baby. The second is the "W triangle design" adopted under the guidance of experts. It's gentle on the body even when carrying the baby, so your shoulders and waist are comfortable. The third is the "Mama's arm carry" that allows you to carry the baby at an angle close to the mother's natural carry during the newborn period before the baby can hold their head up. You can carry your newborn with peace of mind. In addition, there are many other ideas to protect and care for the baby's immature body. With the Ashiraku Support (patent pending), the baby's legs are in a natural shape. If you attach the included head support, you can rest assured even when you want to support the neck or when the baby is asleep. And, ultra-mesh with excellent breathability is used for the back part where the baby tends to sweat. Of course, it can be washed in the washing machine, so you can always use it clean. ◆Accessories ○Main body ○Holding pad ○Instruction manual ○Head support ○Support belt ○Sleep curtain ○How to wear it on YouTube Search for "Aprica Koala Ultra Mesh" and it explains it in an easy-to-understand way!
