Liquid Chalk Markers, 15 mm

For teachers, artists, café owners and anyone decorating car windows, this set is aimed at bold, temporary writing on non-porous surfaces.

Each of the eight markers contains 28 g of water-based ink. The rectangular nib is designed to make broad, bold or fine lines, depending on how you hold it.

There is a little setup before the first mark: shake each marker with the cap on, then prime the tip on a paper towel. That extra step helps get the ink flowing and reduces the chance of drips when writing vertically.

Technical details

The set includes eight liquid chalk markers with a 15 mm jumbo, rectangular nib. Its three usable edges offer different line widths, so you can switch from large lettering to smaller details without changing pens. The ink is water-based and washable, and the markers are intended for non-porous surfaces such as glass, windows and boards.

The product information lists 28 g of ink per marker, which is useful to know if you expect to make large signs or use the set regularly. It does not specify an exact line width for each nib edge or how long a design will last, so those details are best treated as variable rather than guaranteed.

Getting the most from it

These markers suit temporary messages and artwork on glass, car windows, mirrors and boards. For example, a café could use the broad face for a daily menu heading, then turn the marker to add smaller details beside it. They are also described for school boards, office calendars and DIY projects.

The key distinction is the surface: porous materials can absorb the ink and leave ghosting. A more permanent paint marker may make more sense for work that must last, but this set is aimed at washable designs on suitable surfaces. Test a small, hidden area first, especially if you are unsure how a surface will respond.

Usage tips

Before writing for the first time, shake the marker with its cap on. Gently press the nib back and forth on a paper towel for 10 to 30 seconds, until ink flows, then write smoothly. The instructions also recommend priming over a paper towel to catch excess ink.

For car-window designs, let the writing dry for five minutes before driving, and avoid car washes while the design is still on the glass. To remove the ink, use a wet wipe or damp cloth. Es buena opción si you want noticeable lettering that can be wiped away from a non-porous surface, it is less suited to materials that absorb liquid or to artwork that needs to stay put.

Buying questions

Can I use these markers on any chalkboard? They are specified for non-porous surfaces. Since the listing warns that porous surfaces can absorb ink and leave ghosting, test a discreet spot before writing on a board.

How do I get the ink flowing? Shake the marker with the cap on, then gently pump the tip on a paper towel until ink appears. This first-use preparation takes 10 to 30 seconds.

Can I erase the writing? The water-based ink is described as washable and can be removed with a wet wipe or damp cloth from suitable surfaces. The instructions do not promise the same result on porous materials.

Before buying

Choose these if you want a set of eight markers with a broad, multi-edge nib for temporary lettering on glass, windows or other non-porous boards. The main trade-off is surface sensitivity: porous materials may retain traces, and car-window designs need drying time and should stay clear of car washes. Puede no ser la mejor opción si your project involves porous surfaces or needs permanent writing.
