Quick answer

If you already know the ink, tip size, and barrel you like, single pens are usually the better buy: you pay only for what you'll actually use, and you can replace one pen at a time. A pen set only wins when the per-pen price beats buying individually and you'll genuinely use most of the pens. For journaling and everyday lists, two or three single pens you love beat a ten-pen set where half sit untouched.

What a pen set actually costs you

A set feels cheaper because the per-pen price drops, but that math only holds if every pen gets used. A five-pen set at a low per-pen price can still cost more than one pen you reach for daily, because the unused pens are money sitting in a drawer. Before buying a set, divide the total price by the number of pens you're confident you'll use, not the number in the box. If that number is close to the price of a single pen, buy the single pen.

Single pens: fewer decisions, faster replacement

Buying one pen at a time lets you match the exact tip size and ink you want, and replace just that pen when it runs dry. It also makes it easy to try a new barrel color or phrase without committing to a bundle. The trade-off is that you may pay slightly more per pen, and if you like variety, you'll need to buy several singles to get it. For journaling, where you often want one reliable pen for long sessions, this is usually the better path.

When a pen set is the smarter buy

A set makes sense when you're buying for a group, stocking a shared desk, or you genuinely switch ink colors or tip sizes within a single project. It also helps if you're new and want to test several options before settling on a favorite. The catch is that sets rarely let you choose the exact mix, so you may end up with pens you'd never pick alone. Check whether the set's pens share the same ink and tip size; if they do, you're buying duplicates, not variety.

Refillable pens change the comparison

Refillable pens shift the math: a higher upfront cost can pay off if you write daily and the refills are easy to find. The trade-off is that refills add a recurring cost and a dependency on the refill staying in stock. If you write in short bursts or lose pens often, a simple disposable pen is the lower-risk choice. If you journal most days and keep track of your things, a refillable pen can be the better long-term value.

Trade-offs at a glance

  • Cost per pen: Sets lower the per-pen price, but only if you use every pen. Singles cost more per pen but you buy only what you'll use. Do the per-used-pen math before buying a set.
  • Choice and control: Singles let you pick the exact ink, tip size, and barrel. Sets lock you into a fixed mix that may include pens you'd never choose. If you know your preference, buy singles.
  • Replacement and upkeep: Singles are replaced one at a time. Sets leave you with orphan pens when one runs dry, and refillable pens add a refill dependency. Match the format to how often you write and how well you keep track of pens.
