Instructions regarding usage and storage of fabric markers don’t differ much and can be found in the description leaflet of the product. You should not expose the markers to air for a long time. For this reason, close the cap quickly after usage to prevent the evaporation of the ink, which can cause markers to dry out. Also, always put the fabric markers vertically with the capped nib downside so that the ink is always at the nib, and they’re ready to go. Finally, it’s advisable to use the fabric markers on a fine quality cloth because the granular fabric can affect the nib of these markers.
