For anybody trying to shop for pens in Houston, TX, apart from a few shops in the Galleria and Dromgoole's in the Rice University Blvd. area - I discovered this store on Greens Road (East) in North Houston (Highway 45).
They have an interesting assortment of Parker, Cross, Tomboy, Viscounti, Retro 51 and Conklin. They also have inks and a large selection of pencils and refills.
