These are polypropylene hangers from MUJI (Ryohin Keikaku). The neck of the hanger is curved, making it very easy to use as it prevents the collar from stretching when putting clothes on the hanger. I believe this is the initial model. This is the smaller size of the two sizes available at MUJI. Shipping costs extra, so I can't lower the price much, but I'd like someone to use them, so I'm selling a set of 4, which is the total of 3 hangers per set.
