The sight of the baby wearing it was adorable, but the baby didn't like it, so it was only used a few times. It's in clean condition. [Adjustable Size. Straps Improved Based on Customer Feedback!] The shoulder strap belts can be freely adjusted to match the baby's growth. The straps are covered with soft cloth, reducing the load on the baby. Also, the durability of the straps has been increased, making them less likely to break. Generally, it can be used from around 6 months old, when the baby starts to sit up, to around 2 years old, when walking becomes stable. A slip-prevention belt is attached, securing the backpack for peace of mind. Brown bee/Yellow bee: 35cm x 19cm, thickness 5.5cm or more (head part) [Above All, Cute] This is a bee-themed backpack that became famous for its cuteness in a certain commercial. The already cute baby becomes one with the bee, and as a parent, you won't be able to stop smiling. Perfect for celebrating when your baby can sit up, touch things, or start walking! It's also sure to be Instagrammable. [Thorough Shock Absorption] Babies who have started to stand or walk really need constant supervision. Even if you are watching, they tend to bump their heads when they fall. In case the baby hits their head hard, a baby head guard is recommended as insurance. With a thickness of 4.5cm or more and filled with padding, it absorbs shocks effectively. [Mesh Material for Excellent Breathability! Lightweight and Doesn't Burden!] Mesh material suitable for spring, summer, and autumn. No more sweaty backs! The main body is also lightweight at 160g, so it doesn't put a burden on the child even when worn. #HeadBumpPrevention #CushionBabyHeadGuard #BabyFallPreventionBackpack #BumpBabyBee #BackpackBee #FallPrevention #Backpack #Baby #Bee #Cute
