Written by Robert S. Brown / Fact checked by Helen B. Harris

how long do expo markers last

Three factors need to be considered to determine how long do Expo markers last. These are:

  • How often the Expo marker is used.
  • How the Expo marker is stored.
  • Type of Expo marker.

According to Expo, their markers could last up to 3 years if the markers are not in use and are stored correctly with caps tightly closed in a horizontal position.

This question is quite common for users as markers do not usually have expiry dates printed on their labels. Now let us get to the details of each factor.

Expo Markers: How Long Do They Last?

1. Depending on the marker usage


Some markers could last for ages as long as it is stored properly. In a classroom set-up where markers like dry erase markers are continuously used, it could last up to 2 years given that it is well kept.

Moreover, instances like markers drying out too soon are unavoidable.

Check the FAQs section below on how you can revive Expo markers and how you can make them last longer.

2. Depending on how they are stored


Mostly taken for granted but storage is the culprit or could be the main reason why some Expo markers dry out even though it is still new.

Most markers are stored in receptacles where they are held upright with tips up or down. This storage is fine with pens but if we talk about markers, they should be stored horizontally.

3. Depending on the type of Expo marker


There are two types of Expo markers: dry-erase markers, commonly used for whiteboards, and wet-erase markers, which are best for labeling.

Dry-erase markers were made with an alcohol-based formulation, while wet-erase markers were made with a water-based formulation.

With that, dry-erase markers could be more sensitive to heat and dry out faster.

Frequently Asked Questions
