Sakura Craypas Ball Sign ID 3C Review: A Three-Color Multi Pen Built Around Black

Introduction

Most multi pens split their slots between black, blue, and red. Sakura Craypas took a different route with the Ball Sign ID 3C, released in October 2023: a three-color pen built around black itself, pairing two distinct shades of black with one accent color. Priced at 935 yen tax included, it is the multi-color version of the single-color Ball Sign ID Plus line, and it won recognition in the 2022 Stationery Awards for its color-focused concept.

The idea sounds niche until you think about how people actually write. If your pen spends its life in a planner or a notebook, having two blacks on hand makes far more sense than a blue you rarely reach for. After spending time with the pen, here is how it stacks up.

Who This Pen Is For

The Ball Sign ID 3C is aimed at business and everyday writing, and the design makes that clear. The barrel comes in black or white, both with a simple, understated finish that would not look out of place in an office.

It suits planners and heavy note-takers above all. Anyone who has run a multi pen dry on black only to find the blue nearly untouched will appreciate a configuration that puts the most-used color first. Three refill combinations exist: pure black, blue, and red (the most standard pairing), night black with pure black and red, and forest black with pure black and red for a black-black-red setup.

Design and Build Quality

The barrel uses ABS resin with a smooth, dry feel rather than the rubberized coating found on the Ball Sign ID Plus. Despite the bare plastic, the surface quality is genuinely high, and the back of the barrel carries embossed “Japan Ball Sign ID” lettering. The metal tip cone tapers in a straight line toward the ballpoint, matching the design language of the ID Plus.

The clip is on the softer side but does not extend very deep, so it stops partway down. At 146mm long, 13.3g, and 11.5mm in diameter, the pen is light in the hand and well balanced near the center, which reduces fatigue over long sessions.

The knock mechanism is a slide-lever design: pushing a small colored lever down extends or retracts the refill. The color markings are kept deliberately tiny and simple so they do not spoil the look, which is a thoughtful touch. The section your finger hooks onto is a narrow protrusion finished in elastomer, giving just enough grip for something with such a small contact area.

Writing Performance and the Refills

The refills are a proprietary 0.4mm oil-based design with a resin ball, and they define the writing experience. The pure black has a distinctly scratchy, textured feel on paper, and the fine 0.4mm tip amplifies that sensation. This is the most polarizing aspect of the pen.

The blue, by contrast, lays down a stable ink flow and produces clean, precise lines that suit smaller characters. The red performs consistently as well. With three refills in one barrel, the tips do create a slight molded collar at the writing end, though it stays within acceptable limits.

One practical note: the refills use a resin ball that should be removed cleanly before first use. And because the refill is Sakura Craypas’s own design, it cannot be swapped for third-party alternatives, so the scratchy character is something you live with rather than fix.

Things to Consider Before Buying

Two aspects of the barrel shape divide opinion. The cross-section combines hexagonal and rounded curves with subtle edges, and it can be hard to find a comfortable grip position. The smooth ABS surface, combined with that shape, also makes the pen slightly slippery during long writing sessions.

The refill itself will be the deciding factor for most buyers. If you enjoy a smooth, gliding ballpoint, the crisp, scratchy feedback of Sakura Craypas’s oil-based ink may take adjustment or simply not suit you. That said, the 935 yen price is reasonable for the build quality on offer, and the knock feel, balance, and finish are all a step above what the bare-resin appearance suggests.

Buying Advice

If your daily writing leans on black ink, whether in a planner, notebook, or office documents, the two-blacks-plus-one concept is genuinely useful and hard to find elsewhere. Choose the pure black, blue, and red version for the most versatile setup, or the night black and forest black editions if you prefer an all-dark palette with a red accent.

If grip comfort and silky-smooth ink flow are your top priorities, test the writing feel first or look elsewhere, since the refill is proprietary and the barrel shape takes getting used to. For everyone else, this is one of the more original three-color pens available at this price.

Conclusion

The Ball Sign ID 3C earns its place through a clever idea executed with care: two blacks where you would normally find black and blue, a light and well-balanced body, and a refined knock mechanism that hides its markings beautifully. The scratchy refill and the awkward grip shape are real quirks, but the overall quality at 935 yen is high, and it is a pen that works hard in a planner without demanding attention. If the concept appeals to you, it is well worth a closer look.
