I've made a few of these now. I like to use gemstone to brighten them up a little. While they're not big sellers for me I have sold 5 or 6.
They are a nice kit and easy to work with. My wife has added Swarovski crystal to the cap on a couple of them to "bling" things up. I usually replace the ballpoint with a gel refill.
Not sure how new a kit they are. I've started making them the beginning of summer.
