This is Akky Sling by Nico Baby. I purchased it around February 2024, recommended by a midwife, but I couldn't use it very well, so I haven't used it much. It's a versatile green color suitable for both boys and girls, so I recommend it to dads as well. I have washed it once before listing it on Mercari. I believe it is in good condition, but please understand that it is a used item stored in a private home before considering a purchase. When shipping, I will package it in plastic to prevent water damage and send it via anonymous delivery. Thank you.
