This is a very stylish sling made with a muted blue-gray cotton-linen fabric and matte black rings. I learned the benefits of slings when my child was born, but I couldn't find one I liked, so I made my own. The rings are from a specialized sling ring manufacturer in the United States. The fabric is a sturdy blue-gray cotton-linen. It's sewn securely, so there are no issues with strength, and I've used it myself. It was a great item for quick babywearing at home when I didn't have time to put on a wrap-style sling. It allowed me to hold my baby close, creating a snug fit, and making both of us happy. The generous fabric also helps with discreet breastfeeding. I think it has a color scheme that's not often found in Japanese slings, similar to stylish overseas items, so I hope someone who likes it will use it. Thank you for looking.
