Review (1/5): Very disappointed
I had been looking for these for some time and was excited to try it and was totally disappointed. You have to press down VERY hard to get the stones to go inside the pen. The tip bends as if it is going to break and it only took in about 4 of 5 stones and I noticed they were in the chamber but in all kinds of directions. Then when I pressed the lever down, the stones got stuck at the opening as they piled up there. I'll stick to my wax stick.
