What to know before buying
Listing details to confirm
Listing details are contradictory or inconsistent: 6 mm appears in the title and line-size field, while the model contains “3mm” and the item-dimensions field says “19 x 14 x 2 millimeters.” Water resistance is listed as “Waterproof,” but another field says “False.” The description says marks erase on non-porous surfaces and may persist on porous ones. Confirm the selected variant and test an inconspicuous area before use, especially on chalkboards.

Frequently asked questions
Can these markers be erased from glass?
The listing says ink can be wiped from non-porous surfaces such as glass with a damp cloth. Test a small area first because cleanup may vary by surface.
Can I use them on wood or paper?
The listing names porous surfaces including wood and paper, but warns they can be difficult to erase and may retain ghosting or residue.
What tip size and style are listed?
The title and line-size field specify 6 mm. The listing describes reversible bullet and chisel tip options, but its model and dimension details are inconsistent, so confirm the selected variant.
How should I prepare and store the markers?
The manufacturer instructs users to shake with the cap on, press the nib until ink flows, test on paper, recap after use and store horizontally.
