How should I store the markers?

• Always recap the marker tightly after use
  Make sure the cap is fully secured to reduce air exposure and help prevent the tip and paint from drying out.
• Store the marker horizontally
  Unless otherwise specified, water-based paint markers are generally best stored flat. This helps reduce uneven pigment settling and prevents the tip from becoming overly saturated or drying out.
• Keep away from heat and direct sunlight
  Store markers in a cool, dry place. High temperatures can accelerate water evaporation and may affect the paint and internal sealing components.
• Avoid freezing temperatures
  Water-based paint should not be stored in freezing conditions, as this may affect the stability of the pigments, binders, and other ingredients.
• Keep the tip and cap clean
  Wipe away excess paint from the tip and inside the cap after use to prevent dried paint buildup from affecting the seal or paint flow.
• Shake thoroughly after long-term storage
  Some pigment settling is normal over time. Shake the marker well before reuse and re-prime the tip if necessary.

In short: keep the cap tightly closed, store the marker horizontally, and protect it from direct sunlight, excessive heat, and freezing temperatures to help extend its lifespan and reduce clogging or tip drying.
