KONNY BABY CARRIER FLEX Charcoal Konny Baby Carrier Flex Baby Carrier Sling Charcoal No original box No instruction manual Size is adjustable from XS-XL, so it can be used by both parents. From 2 weeks old / Newborn 3.6kg-20kg Purchased about a year ago, but It didn't fit my body type, or I couldn't put it on well, I've only used it 2-3 times. Washed with baby detergent. There are no particular stains. We are looking forward to purchases from those who understand.
