pens for agendas?

  1. i bought a small silver pen for my agenda on eBay. it fit the medium mono agenda i have perfectly. but i bought a new red epi agenda and it's too small! it swims in the pen holder!

    does anyone have a medium epi agenda and if so what pen do you use? is the nails agenda the right size or is that too small too? a tiffany one maybe? something else?
