These touch screen writing implements have been covered by me with polymer clay, in one of my signature millefiori designs.
The color and finish is inherent in the clay. No paints or sealers are used, so there is no possibility of chipping. After baking, the barrels are wet-sanded through several grits of sandpaper, and then buffed to a nice, soft, satiny shine. They are exceedingly smooth, and pleasant to touch.
The tip of each touch-screen stylus mimics the touch of a finger, and is handy for those who prefer the feel of writing with a pen.
