Chalkola Dual Tip Liquid Chalk Markers for Blackboard, Chalkboard, Window

Every marker in this Chalkola set has two ends: a 5mm bullet tip and a 1mm fine tip. So one color gives you both a bold headline and the small print underneath, without hunting for a second pen. It costs about $16 and averages 4.4 stars from 5,866 ratings, which puts it behind only the 16-pack of fine tips among the Chalkola sets we cover.

The listing promises a selection of colors but its feature list doesn't say how many markers you get. Confirm the count on the product page before you compare price per pen.

Why dual tips make sense in color

With white-only sets, buying separate thick and thin markers is cheap and simple. Color is different. If you want a red headline with red detail, single-tip packs mean buying red twice. The dual tip solves that, and it's why this set is the pick for colorful menu boards, kids' art and classroom displays.

The bullet tip is also more forgiving than a chisel. It draws the same width in any direction, which helps if you aren't a practiced letterer.

For all-detail work in color, the 16-pack has more colors, including metallics.

Surfaces

Chalkola describes these as glass, mirror and window markers that erase dry or wet from any non-porous surface. On porous surfaces like wood, the ink becomes permanent. The listing also names menu boards, shop windows, whiteboards, LED boards, milestone boards and wedding signs.

Chalkboards need a quick check. Porcelain and sealed boards wipe clean. Plenty of painted boards are porous, and colored liquid chalk can ghost or stain them. Test a small corner first and wipe once it's dry.

The Chalky Crown fridge board is made for liquid chalk. The Loddie Doddie framed board doesn't say either way, so it needs the corner test. More boards, and which take liquid chalk, are in our chalkboard guide.

For kids

Chalkola calls the formula water-based, non-toxic and dustless, and says it wipes off hands without leaving stains. The listing also claims tight-fitting caps keep the tips from drying out. With kids, the caps only help if they go back on.
