Natural Machine Weft Hair provided by us, is a collection of hair that has been machine stitched together. The weft is a little thicker and heavier. Because of the way machine weft is formed, it can be trimmed, making them more robust and sturdier. This is very effective and easy to use. Natural Machine Weft Hair can be simply weaved, bonded, or taped onto your hair. This hair is a little bulkier in packaging, but it can be processed thinner and is more robust.
