Some of my favourite pens have refills! I love my Uni-Ball pens. The fine tip and smooth writing means I always have one with me. Being refillable is a big plus for me and it fits in both the full size pen and the shorter pen. Refills cuts down on plastic waste so I don't always have to buy new pens.
