Make Your To-Do List Unforgettable

Tired of your to-do list blending into the background? These liquid chalk markers make every task pop.

This 20-pack of Bold Chalk Markers offers a vibrant alternative to standard dry-erase pens for anyone using a glass or blackboard productivity system. With a mix of neon and vintage colors, they’re designed to help you color-code projects, highlight priorities, and make your planning boards more engaging and effective. They are perfect for home offices, classrooms, or any space where visual organization is key.

Why it stands out
  • Vibrant and Opaque Colors The neon and vintage colors are genuinely vibrant on dark and light surfaces, making them excellent for color-coding and prioritizing tasks on a productivity board.
  • Versatile Reversible Tip The 6mm reversible tip is a standout feature, allowing a quick switch between a chisel point for bold headings and a bullet point for finer details without changing markers.
  • Simple Wet-Erase Cleanup Cleanup is impressively simple on non-porous surfaces like glass and metal whiteboards, requiring just a damp cloth, but they can leave a faint ‘ghosting’ on some traditional chalkboards.
  • Lengthy Initial Activation Be prepared for a lengthy initial activation; each of the 20 markers requires significant shaking and pressing to get the ink flowing for the first time.

What to look for

Choosing the right Home Office Supplies

  1. Surface Compatibility
    High
    The most critical factor is ensuring markers are compatible with your intended surface. Some markers are designed only for non-porous surfaces like glass, while others work on semi-porous chalkboards but may be harder to erase.
    Look for
    Explicitly lists your surface type (e.g., glass, acrylic, porcelain whiteboard, slate chalkboard). Test on a small, inconspicuous area first.
    Avoid
    Markers that don't specify their erasability on your surface or warn against use on porous materials if that's what you have.
  2. Tip Versatility
    Medium
    The marker tip determines the kind of lines you can create. Reversible tips (bullet and chisel) offer the most flexibility for both writing and drawing.
    Look for
    Reversible tips or packs that include multiple tip sizes (e.g., 3mm, 6mm, 10mm) for different tasks.
    Avoid
    Single-style tips if you plan on doing both detailed writing and bold headings.
  3. Color Vibrancy & Palette
    High
    The quality and range of colors affect the visual impact. Look for opacity, especially for use on dark surfaces.
    Look for
    A mix of classic, neon, or vintage colors depending on your need. High-pigment formulas that provide good coverage.
    Avoid
    Small packs with limited colors if you plan on color-coding or creating detailed art.
  4. Ease of Cleanup
    High
    How easily the marker erases is crucial for frequent use. Wet-erase is standard for liquid chalk, but the effort required can vary.
    Look for
    Formulas that promise 'no ghosting' and wipe away cleanly with just a damp cloth.
    Avoid
    Markers known for staining or requiring special cleaning solutions, especially for high-use boards.
Frequently Asked Questions

Common questions

Are these truly safe for kids to use on windows?

Yes, the formula is non-toxic and odor-free, making them a great choice for activities like decorating car windows for a road trip or home windows for a holiday. Just be sure to supervise to ensure they are only used on glass, as they will not wash out of fabric or other porous surfaces.

How do you switch the reversible tip?

To reverse the 6mm tip, simply pull it straight out of the marker barrel. Flip it over to the desired end (chisel or bullet) and re-insert it firmly. You may want to use a paper towel to avoid getting ink on your fingers during the process.

Will these work on a standard painted chalkboard wall?

It is highly recommended to test on a small, hidden area first. Chalkboard paint creates a porous surface, and while these markers might write on it, they can absorb into the paint and become difficult or impossible to erase completely, causing permanent staining.

Do the colors look good on a white dry-erase board?

Absolutely. While designed for dark chalkboards, the colors are highly pigmented and appear incredibly vibrant on white non-porous surfaces like a glass or porcelain dry-erase board. They provide a much bolder and more colorful alternative to standard dry-erase markers.

Our Verdict

This 20-pack of Bold Chalk Markers is an outstanding value, offering a huge range of vibrant colors and versatile reversible tips. While the initial setup is a bit tedious and care must be taken on porous surfaces, their performance on glass, windows, and quality blackboards is flawless. For anyone looking to make their productivity board or creative project pop, these are an easy recommendation.
