Although we deal with lesser writing instruments on a regular basis, there really is nothing like a fine fountain pen for doing business. The Ohto Tasche Fountain Pen ($20) is unique in its design that allows it to take up much less room than a normal fountain pen when closed, yet still offers a full body when opened. As Uncrate reader Cormac Eubanks told us, "This is a pen that feels and writes like a much more expensive instrument." Sounds good to us. [Thanks, Cormac]
