Is it possible to buy a Schaefer ball point pen refill in phuket.....cheers. I know it's a random question!

Try Central.

I made a switch to Gel Ink Pens, and I love the way they write. Never want to use a ball point pen again. You can get them for about 40 Baht at Big C.

Maybe at Office Max downstairs at Central in the lower level parking area.

B2S has a pen counter.
