Is this product refillable?

Yes they are refillable. Look for BRFV-10EF-B for 0.5 mm refills.

Is this a gel ink or just regular pen?

I nither gel or regular ink, this pen use a hybrid oil based ink, they write very smooth, don't smear, and always write until you deplet the entire ink inside the barrel. You won't be disappointed. I am a nurse, and I don't like to use crapy pens.
