I only have pocket-T's that I wear and my lucky pen goes in that pocket.  I use it for everything to fill out playslips and check tickets with.  The thing about my lottery pen or lucky pen is it loses its powers once it runs out of ink.  So I will usually line up a new pen by then to replace the old one.  The thing to remember about lottery pens or lucky pens they can only have black ink in them or they are not lucky.  The reason being is any other color is not lucky and it will not work.  Why you ask because I said so!-weshar75
