The Pentel RSVP is widely considered a "hall of fame" entry in the world of affordable stationery. If you are looking for a reliable, no-frills workhorse for the office, school, or home, this 12-pack is a classic choice. The signature long, slender barrel is well-balanced. It features a latex-free Comfort Zone™ grip that reduces finger fatigue during long writing sessions. The black ink is smooth and dependable and unlike cheaper ballpoints that "skip" or require a scribble to get started, the RSVP usually writes immediately upon hitting the paper. The 1.0mm medium stainless steel tip is incredibly durable. It produces a bold, clear line that is easy to read without being as "messy" as some gel pens can be. One of its best underrated features is the sturdy metal clip. It’s much more durable than plastic clips and stays securely fastened to notebooks or shirt pockets. It is very smooth for a ballpoint, though not as "slick" as a gel pen. The pens last a long time; you'll likely lose it before it runs out of ink. Dry Excellent for left-handed writers who worry about smudging. With12 pens per pack, the cost-per-pen ratio is hard to beat. While these are disposable pens, they are actually refillable (using Pentel BKL10 refills). This is a nice eco-friendly bonus if you grow attached to the barrel. The Pentel RSVP BK91 is the "Old Reliable" of the pen world. It doesn't try to be flashy; it focuses on being comfortable and consistent. It is perfect for students taking frantic notes or professionals who need a pen that won't fail during a meeting.
