Down Feather
Down feather 10/90 (10% real goose down and 90% duck feathers) is the luxurious choice for most designers and individuals. With the beautiful feathers, the filling makes your pillow keep the best shape. Also, "Feather proof" 100% cotton with 233 thread count fabric is used for the cover of this type of pillow insert. Please be aware that this is NOT a good option for these who suffer from allergies.
