The Sakura Craft Lab 004 is a 3-in-1 multi pen combining black and red 0.4 mm gel ink with a 0.5 mm mechanical pencil. Its anodized aluminum upper barrel, brass grip, and vintage-inspired design make it an appealing choice for anyone who wants practical versatility without giving up the pleasure of a thoughtfully designed writing instrument.
Write your notes, mark what matters, and sketch your next idea. All three tasks can start with the same pen.

What Is the Sakura Craft Lab 004?
The Sakura Craft Lab 004 brings two gel ink colors and a mechanical pencil together in one body. A twist mechanism selects the writing component, while an eraser sits beneath the top cap. It is a compact approach to a familiar everyday problem: needing a different writing tool halfway through a task.
- Black 0.4 mm gel ink for everyday notes and written entries.
- Red 0.4 mm gel ink for annotations, corrections, and visual emphasis.
- A 0.5 mm mechanical pencil for erasable planning and sketches.
- Twist selection rather than separate exposed selector buttons.
- Anodized aluminum upper barrel and brass grip section.
- Body color options: Green, Red, Grey, and Black.
From Meeting Notes to Planner Pages: Why Three Functions Matter
Keep Your Main Notes Clear with Black Gel Ink
The 0.4 mm black gel component is a useful starting point for compact handwriting, planner entries, and meeting notes. When your page has limited space, a fine tip makes it easier to organize detailed information.
Give Important Details Their Own Color
Switch to red gel ink when a deadline, correction, or follow-up deserves a second look. Using a separate color can help you distinguish action items from the surrounding text without reaching for another pen.
Leave Room to Change Your Mind with Pencil
The 0.5 mm mechanical pencil component is suited to tentative schedules, rough layouts, and early-stage ideas. Use it when a plan is still developing, then turn back to ink when you are ready to make a more permanent note.

Vintage Character, Modern Everyday Function
Inspired by the charm of objects such as vintage cameras and eyeglasses, the Craft Lab 004 has a nostalgic character without abandoning modern convenience. Its two-tone construction gives the pen a distinctive silhouette, while the brass clip and Sakura cherry blossom logo complete the design.
The brass grip adds heft near the writing end, bringing the center of balance closer to the tip. That makes this pen worth considering if you enjoy a more substantial feel rather than an especially light plastic body. Comfort is personal, so choose it for the materials and balance you prefer, not just its appearance.
Choose a Body Color That Fits Your Desk
TTpen lists the Sakura Craft Lab 004 in Green, Red, Grey, and Black. The choice is the exterior body color; the writing functions remain black gel ink, red gel ink, and pencil.
Choose Green or Red for a more expressive desk accessory, or Grey or Black for a quieter look alongside a notebook or work planner. Check the product page for the current selection and availability.

A Simple Three-Function Writing Routine

The appeal is not just carrying fewer tools. It is having the right kind of mark ready when your thinking changes.
