What is the sticky Square?

Our square sticky note is the shape everyone knows, with one difference you’ll notice every day: you’ll never throw it away. Thanks to our vacuum technology, it sticks to any smooth surface—from computer screens to refrigerators—without glue or an adhesive edge, and you can move it as often as you like.

Finished with your note? Wipe it off with a cloth and a little water, and there’s room for the next one. No more stack of paper notes that slowly dwindles—just a notepad that can be used over and over again.

Here's how it works

  • 1 of 8

    remove the protective film

    Peel off the backing film and activate our innovative vacuum technology.

  • 2 of 8

    stick

    Press it onto a smooth surface. No water, no glue, no holes. The vacuum technology keeps working, no matter how often you move it.

  • 3 of 8

    peel off

    Grab it by a corner and gently peel it off. No glue residue and no damage—the surface stays clean.

  • 4 of 8

    write

    Write with a whiteboard marker. We recommend Staedtler; its ink dries quickly so you won’t smudge what’s already written.

  • 5 of 8

    erase

    Erase it with the back of the pen or a slightly damp cloth. If you run your hand over it, nothing will come off.

  • 6 of 8

    clip your pen

    The clip attaches using the same vacuum technology. Your pen hangs next to your planner instead of sitting in a drawer.

  • 7 of 8

    plan visually

    Stick a picto on something that happens every week. Sports, work, birthdays—you’ll recognize your week at a glance.

  • 8 of 8

    Highlight with tabs & marks

    Add a word to it: a name, a task, a reminder. Removable, so your week simply moves along.

Will it stick at your place?

Our boards use a vacuum, so they don’t require glue or magnets. They stick to virtually any smooth, clean, and dry surface: from the refrigerator to a door, a window, or a cabinet door.

  • sticks right away

    refrigerator

    It also works on the smooth fronts and sides of built-in refrigerators. Just degrease the surface, and the board will stick.

  • sticks right away

    glass and mirrors

    Windows, mirrors, glass doors, and glass splashbacks.

  • sticks right away

    varnished wood

    A painted door, a cabinet door, or a painted tabletop. Both high-gloss and satin finishes work well.

  • sticks right away

    painted wood

    A painted interior door or cabinet door. Paint on wood stays put, even if it’s matte.

  • sticks right away

    Kitchen cabinet fronts and cabinet doors

    High-gloss and satin-finish fronts for kitchens, bathrooms, and closets.

  • sticks right away

    plastic and laminate

    A laminate countertop, a plastic cabinet door, or a coated furniture panel.

  • sticks right away

    tiles

    Smooth wall tiles in the kitchen or bathroom. It sticks just fine even over grout lines.

  • sticks right away

    metal and stainless steel

    A steel cabinet door, a range hood, or a powder-coated locker. Brushed stainless steel is also no problem.

  • sticks with film

    Matt anti-fingerprint kitchen fronts

    Special anti-fingerprint fronts, such as IKEA VOXTORP matte or KUNGSBACKA, tend to come loose. But if you put Sticky Film underneath, it stays in place.

  • sticks with film

    Unvarnished wood with an open grain

    Unvarnished oak or veneer that lets you feel the grain. Sticky Film creates a smooth surface.

  • sticks with film

    fine-grained wood

    Fine-grained wood such as ash or pine. It often adheres right away, and if not, it will stick if you place Sticky Film underneath.

  • Doesn't stick

    wall paint and wallpaper

    Paint sticks well to wood, but not to a wall: the paint will come off when you move the board. Choose the door or cabinet next to it.

  • Doesn't stick

    textured wall and plasterwork

    There’s too much air between the board and the wall. Even with film, it doesn’t work. A smooth door in the same room does work, though.

  • Doesn't stick

    Untreated wood

    Rough, porous wood such as scaffolding wood or an untreated plank. Varnished or painted wood is no problem.

  • Doesn't stick

    brick and concrete

    Too coarse and too porous to create a vacuum. Find a cabinet door, window, or refrigerator nearby.

Frequently Asked Questions

How do I apply my sticky products?

There’s a protective film over the rubber back of your sticky, so it stays clean for your first use. Peel off this film and make sure the back stays dust-free. If the protective film has already been removed, check to see if there is any dust on the back. If so, clean the back with a slightly damp cloth.

Stick your sticky to a smooth surface. Thanks to vacuum technology, it adheres effortlessly to any smooth surface. So make sure you position it straight, because once it’s on, it won’t slide around. Did you end up hanging it crooked after all? Peel it off with one hand, so you don’t damage the sticky, and reapply it. Keep doing this until it’s perfectly straight :)

Help! My GreenStory sticky isn't sticking anymore. What can I do?

GreenStory sticky's feature our innovative vacuum technology that lets them stick to any smooth surface. Is your sticker no longer sticking? Don’t worry—there’s probably just a little too much dust on the back. You can easily fix this by wiping the back with a slightly damp cloth and then reapplying your sticky to a smooth surface.

Please note: the surface must be smooth! You cannot use the sticky's on rough surfaces such as plastered walls, wallpaper, concrete, or brick. sticky also won’t adhere well to a matte or anti-fingerprint coating without our repositionable backing film.

Can I write on GreenStory products with any whiteboard marker?

Yes, you can definitely do that. In principle, the ink from any erasable whiteboard marker can be removed with a cloth and a little water. Of course, we’ve tested all the different brands of markers ourselves and always come back to one favorite: the Staedtler Lumocolor Non-Permanent 305 F and M. These markers are available in black, blue, and green. They dry quickly, and the organisch water-based, erasable ink doesn’t smudge.

What is your vision?

Our vision is that even a small change can be life-changing. It starts the moment you decide to bring order to the chaos by creating clarity. Because clarity creates insight, and insight creates space. space for good ideas, new habits and balance. We help you take this step in your life with our thoughtful and sustainable designs.

How long will it take for my order to arrive?

Shipping takes 1 to 2 days within the Netherlands and 3 to 5 days internationally, depending on your location. Shipping is free to most European countries on orders of €80 or more.
