Some erasable highlighters use a thermo‑sensitive ink that becomes colorless when heat is generated by rubbing or the supplied eraser; that color can return if the ink cools. Other marker types in this category are formulated for nonporous surfaces and simply wipe off with a damp cloth or eraser designed for that surface.
These write-on/wipe-off tools are intended for nonporous surfaces such as dry‑erase boards, glass (windows and mirrors), and chalkboard surfaces; individual marker listings typically specify whether they’re for dry‑erase, glass, or chalkboard use.
Thermo‑sensitive erasable inks are not suitable for legal or official documents because they can become colorless with heat (and may revert on cooling). Chalk markers can stain porous surfaces, so test them on an inconspicuous area before widespread use.
These activity books use wipe‑clean pages so children can trace and practice repeatedly. They typically include a wipe‑clean marker with an eraser and a wire‑o spiral binding that lays flat for easy drawing and tracing.
Colors range from bright multicolors (yellow, orange, pink, green, blue, purple) to pastel shades and assorted ink colors. Tip styles mentioned include fine points (one fineliner lists 0.7 mm), 1.0 mm and 1.6 mm sizes, as well as chisel and other fine‑point descriptions.
The board listings note accessories such as dry‑erase markers, plastic magnets, push pins, mounting hardware, and a cork/pin strip.
Chalk markers on glass and chalkboard surfaces wipe clean with a damp cloth. Dry‑erase board marks are described as wiping clean easily with minimal ghosting; some listings also include markers or erasers among the accessories.
