“These pens are easy to make and easy to use. The kits are inexpensive but produce a fine looking writing instrument. With the last batch, I did find a problem with the refill getting stuck in the nib opening and when retracted would pull the cap off the refill. I overcame this by inserting the refill tip into the opening from the outside and wiggling it a few times. This seemed to free up the tight fit and worked perfectly.”
