What is the sticky 75-Day Challenge Board?

You don’t just start a 75-day challenge on a whim. You make a commitment to yourself: to exercise, read, drink water, or whatever your goal may be—every day. Our 75-day challenge board hangs where you’ll see it every day, letting the streak grow, day after day.

Those 75 days aren’t just a random number: according to research from University College London, it takes an average of about 66 days to form a new habit. So with 75 days, you’re giving yourself plenty of time. And if you miss a day along the way? No big deal—that same study shows that’s okay, too. Just check off the next day.

Thanks to our vacuum technology, the board sticks to any smooth surface.

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

What’s the best way to establish a good planning routine?

Start small and make it visible. Hang your planner in a spot you walk past every day, give your pen a designated spot, and choose one set time to fill it out—for example, Sunday evening or with your first cup of coffee. The planner takes care of the rest: what you see every day, you’ll stick with. And if the week doesn’t go as planned? Erasing and adjusting is all part of the process. A routine doesn’t have to be perfect—most importantly, it has to be yours.

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 :)

Why choose pictograms for your planner?

Because a picture reads faster than words. With pictograms, everyone in the house can see at a glance what’s coming up—from sports to birthdays—even those who can’t read yet. But it’s also great for those who’ve been reading for a while: it’s perfect for quickly putting up the pictograms for recurring events like sports classes or grocery shopping.

And since the pictograms are just as repositionable as the planner itself, you can simply move them around if swimming lessons get moved to Thursday. There are over 70 of them, so there’s a pictogram for every occasion.

What is your vision?

We believe that a small step can change your life. It begins the moment you decide to bring order to the chaos by creating clarity. Clarity creates insight, and insight creates space: for good ideas, for new habits, for balance. We facilitate that step with our thoughtful and sustainable designs.

Are the products magnetic?

No, and that’s a good thing: magnetic boards only stick to steel, are extremely heavy, and either slide around too easily or not at all. Our sticky products do stick to a steel surface—but not because of a magnetic field, but thanks to our innovative vacuum technology. That’s why they adhere just as well to other smooth surfaces, such as smooth-painted wood, tiles, or a windowpane.
