Just got a heirloom cap grey charcol capilliary filled parker 61. It arrived just last night from Quetta - the capital of Balochistan Province. Paid Rs. 5000.00 ($49.00) for the pen. It is my first capilliary filled P61. The filler as well as the overall pen is in good condition. Do I need take any special care of the pen before I fill it and start using it?
