Our sling rings are staples in our house! We have the bronze in M and L and they work so well for lightweight wraps (like Kipos Hemp) and thicker wraps (like Trias Chai and Trias Chocolate). When a new wrap comes home, or after a wash, I put on a movie and sit down running the fabric through the rings - so relaxing! The rings are light and strong, mine have scuffed a tad, but that's because they also make GREAT play bracelets for toddlers!
