Although I figured out that my Sheaffer Craftsman takes in the standard #15 pen sac from PenSac Company, I still have following questions,
1. Which is better - necked pen sac or the regular tubular pen sac?
2. Is it mandatory to apply sac cement or I can stretch opening of sac and rely on its elasticity and the barrel opening to keep it in place?
3. What causes a leaky Sheaffer? Is the correctness of installing pen sac directly proportional to ink leaking from feed area?
Thanks for reading.
