The blanket envelope “Kantik” is an original product, as it is made from pieces of coarse calico of different colors, sewn in an hourglass shape, highlighted by a beautiful cotton edging and framed with a frame of printed coarse calico. The envelope is made for the convenience of extracting the filler during the wash, on the snake-zipper. The envelope also represents a universal product and can be used as a duvet, and with the help of a bow on an elastic band as an envelope for a baby. The elastic has an optimal size for easy fixation of the envelope.
