Pitamaru Colour Guide — Magfine
MAGFINE — PITAMARU

One magnet.
Built to be seen in colour.

Neodymium-core magnets, coloured and coated in the same tradition Magfine has built magnets on since 1986.

01 — Colour

Ten colours. One consistent magnet.

Pitamaru's palette runs from classic primaries to the kind of muted tone you'd normally only get from custom paint. Same core, same hold — only the coating colour (and the size) changes from one to the next.

02 — Engineering

The colour is a coating. The pull is a 4-pole field.

Underneath every finish is the same rare-earth core Magfine has supplied since 1986 — now magnetized in an alternating 4-pole (N·S·N·S) pattern instead of a simple single north/south face, so the field concentrates right where these actually get used: at the surface, on contact.

03 — Safety

A coating that's food-grade, not just painted plastic.

Most coloured magnets are coated in ordinary PP (polypropylene) plastic. Pitamaru is coated instead in a food-grade French nylon powder — a step up in material quality, not just colour.

Food-grade French nylon

The coating is a French-manufactured nylon powder, food-grade by standard — a different material from the painted plastic shell most coloured magnets use.

Comfortable for everyday handling

A smooth, food-grade coating that holds up well to frequent handling, at home or in a classroom.

04 — Sizes

Two sizes, shown at actual scale.

Every size on this page is drawn to the same pixel-per-millimetre ratio, so the two magnets below are proportional to the real 18mm and 30mm parts — including how visibly thicker the smaller one is relative to its width. The ruler underneath is marked in real millimetres, at that same scale.

05 — In Use

Wherever something needs to hold — and look good doing it.

Same magnet, three shelves it might actually end up on.

Ten colours doubles as ten categories — pin projects, files, or priorities to a magnetic board and sort them by colour at a glance.

Fridge & office

The 4-pole core concentrates its pull right at the surface — strong enough to hold a stack of photos flat against a steel door without sliding, even at 18mm.

Strong enough to hold a paperclip on contact — as at home in a pen cup as on a fridge door.

06 — FAQ

Common questions, answered directly.

Everything shoppers usually want to know before picking a colour.

Are Pitamaru magnets strong enough for a fridge?

Yes. Each Pitamaru magnet uses a 4-pole neodymium core, which concentrates the magnetic field right at the point of contact instead of spreading it across the whole disc. That gives it a strong, snappy hold on a steel fridge or whiteboard door — enough to hold a stack of photos or papers flat without sliding, even at the smaller 18mm size.

Can Pitamaru's colours be used for colour-coding or organization?

Yes. The ten-colour range — from primary reds and blues to softer, muted tones — makes Pitamaru well suited to colour-coding projects, files, or categories on a magnetic board, in addition to simply holding things up.

What's the difference between the two Pitamaru sizes?

Pitamaru comes in two disc diameters, 18mm and 30mm, in all ten colours. The 30mm size gives a larger colour surface and a stronger overall hold; the 18mm size is more compact for lighter items or tighter spacing.

What is the coating made of?

Unlike most coloured magnets, which are coated in ordinary PP (polypropylene) plastic, Pitamaru is coated in a food-grade French nylon powder — a step up in material durability, not just colour.

Is Pitamaru safe to have around children?

Like any small, powerful magnet, Pitamaru should be kept away from young children — swallowing more than one small magnet can cause serious injury. These are designed for office, studio, and home organizing use, not as a children's toy.

Pitamaru — colour that holds.

Ten colours, two sizes, one neodymium core. Built by Magfine, the same team that's been making magnets in the Japanese tradition since 1986.
