For an item that was made specifically for use with the Distress Markers, it seems really silly that it is NOT to be used while standing upright. The side of this container has labels on it that states the markers must be stored horizontally. If this is the case, shouldn't the storage case be made NOT to roll around?
What a perfect container for pencils, paintbrushes, pens, etc. I use my for my craft items on my work staion and couldn't be more pleased. I like you can see what you have w/out having to dump the contents. Great container.
