Compare the Karas Pen Co CUBE and reKtangle pen holders to find the best desk storage for your collection. We break down design, capacity, and use cases.
If you own more than a few pens, you know the struggle of keeping them organized. A dedicated pen holder not only protects your writing instruments but also turns your desk into a more functional, stylish space. Karas Pen Co offers two popular desk storage solutions: the CUBE and the reKtangle. Both are machined from solid materials, but they serve different needs. In this comparison, we'll break down their design, capacity, and best use cases so you can choose the right one for your desk.
Whether you're a collector with dozens of pens or someone who just wants a tidy workspace, understanding the differences between these holders is key. Let's dive into the details.
Design and Build Quality
Both the CUBE and reKtangle are machined from aluminum and feature a clean, modern aesthetic that complements any desk. The CUBE is a compact, cube-shaped block with a single large cavity that can hold multiple pens in a bundle. Its minimalist design takes up minimal desk space and works well as a standalone piece.
The reKtangle, on the other hand, is a rectangular block with precisely drilled holes — the 21-hole version holds up to 21 pens individually. It has a more substantial footprint but offers better organization because each pen gets its own slot. Both holders share the same premium machining quality and anodized finish that Karas is known for.
- The CUBE is about 2 inches per side; the reKtangle is longer and wider.
- Both are available in multiple anodized colors to match your desk.
- The reKtangle's individual slots prevent pens from scratching each other.
Capacity and Organization
Capacity is where these two holders diverge most. The CUBE can hold roughly 5 to 10 pens depending on their thickness, but they sit loosely in one compartment. This works fine if you rotate through a small set of pens, but it can lead to clutter if you overfill it.
The reKtangle 21-hole Pen Holder offers dedicated slots for each pen, making it easy to grab the one you want without disturbing others. It's ideal for collectors who want to display their pens or for anyone who frequently switches between different writing instruments. The individual holes also accommodate various pen diameters, from slim rollerballs to thicker fountain pens.

- CUBE: loose storage, up to ~10 pens depending on size.
- reKtangle: 21 individual slots, each fits pens up to about 14mm diameter.
- reKtangle is better for showcasing a collection; CUBE is better for quick access to a few pens.
Desk Space and Portability
If desk space is at a premium, the CUBE is the clear winner. Its small footprint lets it sit next to a monitor or in a corner without crowding your work area. It's also easy to move around or toss in a bag if you need to take your pens to another location.
The reKtangle takes up more horizontal space — roughly the size of a small notebook — but its low profile means you can still place it under a monitor riser or on a shelf. It's less portable due to its size and weight, but it stays put on your desk. For a dedicated home or office setup, the reKtangle's organization often outweighs the space trade-off.
- CUBE: fits in tight spaces, easy to relocate.
- reKtangle: requires a dedicated spot, but stays stable.
- Consider your desk layout before choosing.
Which One Should You Choose?
Your choice ultimately depends on your pen collection and how you use your desk. If you have fewer than ten pens and want a simple, space-saving solution, the CUBE is a great pick. It keeps your pens accessible without taking over your workspace.
If you have a growing collection or like to see all your options at a glance, the reKtangle 21-hole Pen Holder is the better investment. It turns your pens into a display and prevents the frustration of digging through a pile. For those who need even more capacity, Karas also offers larger pen holders, but the reKtangle hits a sweet spot for most enthusiasts.
- CUBE: best for minimalists and small collections.
- reKtangle: best for collectors and frequent pen swappers.
- Both are built to last and look great on any desk.
Whether you choose the compact CUBE or the organized reKtangle, you're getting a premium desk accessory from Karas Pen Co. If you're ready to upgrade your desk setup, explore the reKtangle 21-hole Pen Holder to give each pen its own home.
