How long can markers be kept?

Hello: There are two kinds of watercolor pens: oily and water-based. However, oil and water are only different in usage, and they are basically the same according to the storage method.

First, let's see if you often use markers. If you do this, you should close the lid tightly after each use. Don't let the cap combine with air, because both water-based and oil-based markers are volatile, and once exposed for too long, the marker will naturally dry. Generally, an oily marker will react when it comes into contact with air for half an hour.

Secondly, the marker you bought home is not often used, that is, the marker is integrated and placed in the shade. Make sure that every mark is covered tightly. Don't let the sun shine.

There is no way to save the tag for longer. It depends on the shelf life and preservation method of the marker. If it is preserved, it will not be a problem for a year or two, but also depends on the quality of the marker. As my personal cherry blossoms, thunderbolt, touching and so on. It can basically meet the requirements.

But it shows that markers are used for making, and it is a waste to buy them home without using them.

This is basically the case. The nib of the marker should not touch any liquid, which will reduce the use time.
