Bristle Material (Nylon 66)

Why We Chose Nylon 66

​

• The Right Balance of Firmness
and Flexibility

​

Each bristle is 0.8 mm in diameter
and 20 mm long.

​

After repeatedly testing various bristle
materials and lengths in real-world
cleaning work, we selected this balanced
design for professional use.

​

Making the bristles thicker or shorter
increases stiffness, but reduces the
flexibility needed to conform to tight spaces.

​

Designed for professional cleaning,
this product combines the right firmness
to scrub away dirt with the flexibility
to conform to tight spaces.

​

• Excellent Wear Resistance
for Long-Lasting Bristles

​

The bristles resist wear during daily
cleaning and are designed for
long-term use.

​

• Excellent Heat Resistance

​

Also suitable for cleaning
with hot water.

Handle Material (Aluminum)

Why We Chose Aluminum

​

This product is designed to reach
narrow gaps and tight spaces.

​

If the handle were made from resin tubing,
the pressure applied during bristle insertion
could easily cause cracks.

​

Even if no problems were visible during
manufacturing, cracks could develop
during use.

​

To withstand this pressure, a resin tube
would require sufficient wall thickness.

​

With a bristle-hole diameter of approximately
6 mm and a wall thickness of approximately
4 mm, the outside diameter would be
approximately 14 mm.

​

However, as the outside diameter increases,
it becomes more difficult to reach narrow
gaps and tight spaces.

​

For this reason, we chose aluminum,
which allows us to keep the handle slim
while maintaining the required strength.

​

This product is designed to balance
a slim profile with the strength required
for professional use.

Handcrafted One at a Time
by Skilled Brush Artisans

Each brush is handcrafted by
a skilled brush artisan.

​

Both ends of each aluminum tube
are individually chamfered by hand
(a process that smooths the edges)
before the bristles are inserted.

​

This professional-grade pen-style brush
is built to meet the quality requirements
of real-world cleaning work.

*Because part of the manufacturing process
is completed by hand, slight variations may
occur in the fine details of the finish.
These variations do not affect quality
or performance.
