These are our lovely acrylic beads, which we have chosen out of a choice of thousands of contenders - we were looking for something that was beautiful and shining without looking cheap and tacky - acrylic is higher end than ordinary plastic, which can be hard and scratchy. At the end of each bead there is a small 'moulding mark' which is part and parcel of the manufacture of these beads, but these are lovely and clear and look like huge pebbles - we hope you'll like them as much as we do - use one as a focal area for your jewellery, or make an entire bracelet or necklace of them using stretchy thread or ribbon.
