Push a thumbtack or pin into a wall, and a tiny hole is left behind, no matter what.
It's a small "trace" of daily life, but for renters and people who care about pristine walls, it's the kind of thing that quietly nags at you.
The product that silently erases that subtle stress, just like a ninja, is the "Ninja Pin."

| What exactly is the Ninja Pin?

The Ninja Pin is, true to its name, a pin designed to "vanish like a ninja." It features a needle far thinner than that of a regular thumbtack, and a structure that won't leave a noticeable mark on your wall.
Compared to other pins, it offers:
- Holes that are barely visible
- Less damage to wallpaper or plastered walls
- Easy removal and repositioning
These qualities make it a strong ally for anyone who treasures the wall itself.

The true essence of the Ninja Pin is the experience itself: "you can't tell it was ever used."
- Because the needle is ultra-fine
- Because the hole left behind is tiny
- Because it doesn't disrupt the wall's color or texture
Once you've used it, the physical act of "pushing in and pulling out" looks as if nothing ever happened.
This is a kind of invisibility that ordinary pins simply don't have — elevated into a value that defines the tool itself.

Using the Ninja Pin couldn't be simpler.
- Lightly push it into the wall
- Hang a postcard or piece of paper on it
- When you're done, pull it out
In just those few steps, your wall becomes a mini gallery, and your display options open up freely.
And yet, the "thoughtfulness behind that simplicity" is a design that fully understands the mindset of someone who doesn't want to leave a trace.

Let's also lay out the kinds of scenes where it really earns its keep.
- Hanging posters in a rented room
- Temporarily fastening pieces for an exhibit
- Pinning up pamphlets without worrying about wall damage
- Displaying photos or cards to set the mood
In short, it's perfect for people with the sensibility of "keep the memories worth keeping, but don't leave behind the marks you don't want."

The Ninja Pin isn't just an upgraded thumbtack.
It's an especially good match for:
- People who care about the beauty of their walls
- People who want their decor to harmonize with the room
- Renters who still want freedom to decorate
- People who love small, thoughtful touches
The more you carry that subtle sensibility of "I don't want more holes in the wall," the more you'll feel the value of the Ninja Pin.

The Ninja Pin isn't just "a pin for pinning things up." It's a tool designed around the idea of being "a pin that leaves no trace."
The act of pushing it in is the same, but when the visible result changes, the whole experience changes.
It's like a tiny ninjutsu for "lightening the physical act itself" — and that, in essence, is what the Ninja Pin truly is.
