Zebra blen 4+S Macaron Limited Edition Multi-Function Pen | 0.5mm | 4-Color + Mechanical Pencil

Zebra blen 4+S Macaron Limited Edition Multi-Function Pen — 0.5mm | B4SAS88

Five functions. One pen. Zero compromise on smoothness. The Zebra blen 4+S Macaron Limited Edition (B4SAS88) combines four colors of Zebra's signature blen low-vibration ballpoint ink with a built-in 0.5mm mechanical pencil — all housed in a barrel dressed in exclusive macaron pastel colorways. Whether you're color-coding notes, annotating documents, or sketching layouts, this is the one pen that handles everything — and looks exceptional doing it.

Key Features

• blen Low-Vibration Ink Technology — Zebra's proprietary blen formula minimizes the microscopic vibration of the ballpoint tip during writing, producing a dramatically smoother, more consistent line than standard ballpoint ink — the defining innovation of the blen series
• 4-Color + Mechanical Pencil (4+S) — Four ballpoint ink colors (black, red, blue, green) plus a 0.5mm mechanical pencil in a single barrel — five writing functions, one instrument
• 0.5mm Fine Tip — Finer than the standard 0.7mm ballpoint, delivering neater, more precise lines for dense note-taking and detailed annotation
• Quick-Dry Ballpoint Ink — Medium oil-based ink dries rapidly on contact with paper, minimizing smearing across all four colors
• Macaron Limited Edition Barrel — Exclusive soft pastel colorways (B4SAS88) not available in the standard blen lineup — a seasonal collector's release
• Weighted Low-Vibration Tip Design — The blen tip mechanism uses a specially weighted internal structure to absorb tip vibration, reducing writing noise and improving line quality simultaneously
• Made in Japan — Engineered to Zebra's exacting quality standards

Frequently Asked Questions

Q: What is blen ink, and what makes it different from regular ballpoint ink?

A: blen is Zebra's proprietary low-vibration ballpoint ink technology. Standard ballpoint pens produce microscopic tip vibration as the ball rolls across paper — this causes slight line irregularity and the characteristic "scratchy" feel of ballpoint writing. Zebra's blen mechanism uses a specially weighted tip structure to absorb this vibration, resulting in a noticeably smoother, quieter, and more consistent line than conventional ballpoint pens. It is one of the most significant ballpoint innovations in recent Japanese stationery history.

Q: How do I switch between the four ink colors and the pencil?

A: The blen 4+S uses a multi-function click mechanism. Each color and the pencil function has a dedicated selector — press the corresponding tab or button to extend that tip. Only one function is active at a time. The selectors are typically color-coded for instant identification, and the pencil selector is clearly distinguished from the ink colors.

Q: Why is 0.5mm better than 0.7mm for this type of pen?

A: The 0.5mm tip produces a finer, neater line — particularly valuable in a multi-color pen where you're often writing in smaller spaces, annotating margins, or color-coding dense notes. The finer tip also pairs more naturally with the 0.5mm mechanical pencil function, keeping line weights consistent across all five writing modes. For those who prefer a bolder stroke, Zebra also offers the blen 4+S in 0.7mm.

Q: Is the ballpoint ink quick-drying? Will it smear?

A: Yes. The blen medium oil-based ink dries rapidly on contact with standard paper, making it significantly more smear-resistant than gel ink. This makes the blen 4+S an excellent choice for left-handed writers and for use on glossy or coated paper surfaces where gel ink may struggle.

Q: What lead refills are compatible with the built-in mechanical pencil?

A: The built-in 0.5mm mechanical pencil accepts standard 0.5mm mechanical pencil lead refills. Zebra's own 0.5mm leads are recommended, but leads from Pentel, Pilot, uni, and KOKUYO are also compatible. Choose your preferred grade — HB for general use, B or 2B for darker lines.

Q: Is this a genuine Zebra limited edition?

A: Yes. The B4SAS88 Macaron is an authentic Zebra blen limited edition release, featuring exclusive soft pastel barrel colorways not available in the standard blen 4+S lineup. Once stock sells out, these specific colors will not be restocked.

Q: How does the blen 4+S compare to the Zebra KNOCK shake mechanical pencil?

A: These are complementary tools for different needs. The blen 4+S is a multi-function pen — four ballpoint colors plus a pencil in one barrel, optimized for color-coded writing, annotation, and versatility. The Zebra KNOCK is a dedicated mechanical pencil with a shake-to-advance mechanism and low center of gravity, optimized for precision pencil writing and drawing. If you need multiple ink colors in one pen, choose blen 4+S. If you need the best possible pencil experience, choose KNOCK.
