You suddenly notice your smartphone screen is clouded with fingerprints. Your glasses lenses have picked up oily smudges, leaving your vision hazy and white. In moments like these, do you find yourself rubbing them vigorously with the sleeve of your shirt or whatever tissue happens to be nearby?
Unfortunately, that action isn't actually removing the dirt. It's simply spreading the oil into a thin, even layer. Worse still, the stiff fibers or tissue pulp are inflicting microscopic scratches on your delicate lenses and screens. To put an end to the frustration of "wiping it but never getting it clean," there's only one answer: "Toraysee," developed by Japanese chemical fiber manufacturer Toray. It may be just a piece of cloth—but it's a "cleaning tool" born from cutting-edge science.

At first glance, Toraysee looks like an ordinary cloth with a slight sheen. But look at it under a microscope, and its true nature is revealed. Ultra-fine microfibers—just 2 microns in diameter, roughly 1/1600th the thickness of a human hair—are woven together at extremely high density.
Ordinary fibers are too thick; they merely glide over the surface of the dirt. But Toraysee's fibers are so fine that they slip right into the oil film itself. Then, the countless gaps between fibers—known as "micro pockets"—capture the dirt one particle at a time. In other words, it doesn't simply "wipe" the dirt away—it physically "scrapes" it off. That's why no detergents or chemicals are needed. A simple dry wipe is enough to remove oily grime with astonishing clarity.

The first time you actually use it, the difference in feel is striking. You may sense some resistance at first, but that's proof the fibers are catching the dirt. After a few back-and-forth strokes, your fingers suddenly glide effortlessly, and the surface becomes so smooth you can almost hear a clean "squeak."
Take a look at your smartphone screen or glasses lens after wiping. There won't be a trace of oily residue left—it should be as clear as a brand-new pane of glass. The reaction "it's like the world has been upgraded to high definition" is no exaggeration at all.

Some people rely on disposable alcohol wipes or pre-moistened lens cleaning sheets. But Toraysee is "washable." Even when it gets dirty and its cleaning power drops, a simple hand-wash with neutral detergent releases the trapped grime from those fiber pockets, restoring it to like-new performance.
Even after repeated washing, the fibers don't lose their shape, and a single cloth can last for years. They sell for anywhere from a few hundred to about 1,000 yen per cloth—but considering their lifespan, they're overwhelmingly more economical than constantly buying disposable products.

The places where Toraysee shines are practically endless.
- Smartphone screens and tablets
- Computer monitors
- Camera lenses and filters
- Bathroom mirrors and window glass
- Glass faces of luxury watches and accessories
It's especially essential for touchscreen devices, where oily fingerprints stand out the most. Watching videos or viewing photos on a screen completely free of fingerprints offers an entirely different level of beauty. There's a wide variety of sizes too, so we recommend using a small one (such as 19cm × 19cm) for carrying around and a larger one (like 30cm × 30cm) for use at home.

We spend most of our day looking at the world through the lenses of our glasses or the screens of our smartphones. When those "windows" are dirty, they place an unconscious strain on our brains.
Toray's Toraysee removes that stress in an instant and delivers a perfectly clear field of view. One in your bag, one on your desk. Keep this magical cloth always at hand, and you'll be able to see the world in sharp clarity any time you like. It's the simplest—and most effective—form of "rest for the eyes."
