Has anyone made these? I bought 10 kits awhile ago and decided to make a few for an upcoming show. I made one, and all went well until you try and sharpen the lead. There's a plastic tube that sleeves the lead, it's press fit on both ends, the nib end comes already pressed on. When you try and remove the opposite end to sharpen the lead, as that is where the sharpener is, the nib end pulls out and even if you press it back in, the pencil is inoperable. I put in new parts from another kit and it did the exact same thing. I'm thinking this kit is very poorly engineered and I will probably keep the lead and throw the other 8 kits right in the trash.
