This is a 11 cm magnifying glass with 2 x power from Magnifiers NZ. It also has a spot magnifier which is 4 x power. The grey magnifier hangs around your neck on an adjustable cord and the feet rest lightly on your chest, keeping your hands free so that you can stitch with ease. Light weight and good sturdy construction, with the glass big enough to enlarge a good area of your stitching so that you can easily see where you are up to. We have tested this product and found it very easy to use. It could be used for needlework, sewing or any craft & is a great gift idea.
