I give my CW pens to the Master Pen Loser (aka my husband). He seems to somehow lose as many pens as he gets, but black happens to be one of the colours that don't appear very often in our house (one of the locations is my bathroom, which he is frightened to enter as there are so many lotions and potions and other miscellaneous "rubbish" as he calls them), so it's less likely to do a chameleon impersonation on us.

Master Pen Loser's ability is pretty amazing. I eventually find them in some strange corner of the house where they all seem to congregate but I never thought they would do. Anyway, I am not worried what he does with them anyway, so I leave them in his capable hands.

The F ones sit in one of my stationery drawers. Not sure why, but I think I am guarding them from the Master Pen Loser as they are a bit more pretty. I'd dish them out to the MPL if he loses all others.

I carry my own pens - in fact I always have at least 3 pens on me. However, it's handy to have one in the wash bag to complete the forms etc as my bag may be harder to reach than the wash bag.
