I recently purchased several sets of Alcohol markers from Amazon. They are Ohuhu brand.
I purchased 3 different sets but ultimately kept only 2. I gave one set to my daughter.
To organize these according to the swatch cards, in the bags they came in, I used cardboard dividers. Unfortunately this brand, this style, didn't come in boxes.
This was okay although the the markers moved when one was pulled out so this bothered me.
I decided I wanted to purchase boxes for them. But I also wanted the set of pastels (my 3rd set). I bought them first then the box later.
When the box arrived is when my organizing genes kicked in. I want them to be in order together.
Ultimately I purchased 2 boxes.
