Mr. Pen- Liquid Chalk Marker Pen, 4 Pack, 8x Labels, White Non-Toxic Odorless Chalk Markers, Dual Reversible Chisel & Bullet Tip, Ideal for Non-Porous Chalkboards, Chalkboard Vinyl, Glass & Metal

These chalk markers are amazing! They work beautifully on a blackboard, but I mainly use them on our bespoke refrigerator to write notes and reminders. The tip has the perfect thickness, which makes writing neat and easy, and they never spill or make a mess. I love how smoothly they glide and how simple it is to wipe them off—no film or residue left behind. The fact that you get four markers for such a great price makes it an even better deal. If you need reliable chalk markers for a blackboard, fridge, or any smooth surface, these are a fantastic choice. Highly recommend!

As described!! Exactly what I was looking for!

These are great chalk pens. The tip creates sharp clear writing lines that are consistent. Very easy to use. I use these on the adhesive chalk board material attached to metal baking pans like pizza pans and cookie sheets for signs. They last through storage but erase easily. I have been erasing these with slightly damp Mr. Kleen magic erasers.

These were originally to replace the used-up chalk marker for my black "whiteboard" calendar. Like most chalk pens, you sometimes have to shake them a bit or write over spots before you get a good solid line. They also work well on blackboards, for labeling mason jars, etc. They work more like WET erase markers, not dry erase. I actually prefer them this way, as they don't smudge off so easily. Just use a damp rag or a bit of glass cleaner when you're ready to erase, and the ink will come right off.

Works great! They write really well on some blackboard signs I got and they wipe up really easily, too. I did have an overflow problem once I finally got some ink to the tip, and it might be because I had to store it on its end instead of on its side. But once I shook it out over a trash can, it was fine. You can see what I wrote on them from a distance, they dried pretty fast, and no bleeding or feathering. Nice bold writing. I like this brand a lot.

TL;DR: 5 Stars. A high-utility, odorless writing set that effectively replaces dusty traditional chalk with smudge-free liquid pigment. While they offer superior visibility and dual-tip mechanics, they are strictly limited to non-porous surfaces to avoid permanent ghosting. Resulting in potential for professional-grade labeling and signage that remains easily reversible on glass or metal. [The "Service Pro" Assessment: Ease of Use & Appearance] After 20 years in professional environments, I prioritize tools that maintain a clean Appearance without the mess of traditional chalk. These Mr. Pen markers offer incredible Ease of use for desktop organization. The ink is water-based and odorless, making it a "bunker-safe" asset for enclosed home offices. [Mechanical Performance: Drying Time & Color] Drying time: The ink is quick-drying, which is a mechanical necessity to prevent smearing during long technical sketches. Once set, it delivers a high-contrast white Color that is far more legible than standard dry chalk. Leakage: The valve-activated chassis prevents accidental Leakage during storage, provided you keep them horizontal. Tip thickness: The reversible dual-tips (Chisel and Bullet) allow you to toggle Tip thickness between broad signage and fine-line detailing. [Functional Utility: Cleanup & Surface Safety] Erasability: Cleanup is effortless on glass or whiteboards with a simple damp cloth. The "Ghosting" Warning: Technical Note: These are permanent on porous materials like wood or paper. Always test a small area on your chalkboard first to ensure it isn't too absorbent. [Auditor’s Summary] The Mr. Pen 4-pack is a reliable "Tier 1" creative utility. It provides 100% smudge-free lines and vibrant visibility for any dark, non-porous surface. Recommended for users who need precise, erasable labeling for professional or industrial organization.

These bled a little more than I thought they would! But the white paint was very opaque and nice in color! They were easy to wipe off when needed! A decent price for the pack. Easy to write with but like I said they bleed a little so don’t push down too hard!

Muy buenos

These work great. Love the various sizes. We used them for tracing winter scenes on our windows and the kids love them.

Great chalk pens. I bought to decorate my mirrors for xmas. Easy to use. Also easy to remove just wipes off. Definitely recommend

Write well but messy when erasing

Schlechte Qualität, nicht zu empfehlen.

Very good and last a good while too
