First I want to say I love the color of my new pencil case!!! This pencil case is very nice and I like carrying it around with me. I tried out a couple different media inside the case. Colored pencils fit perfectly in each slot. If you are wanting to put larger items like brush markers, you will need to space them about every other slot to make it easier to get them in and out. I love the different sections. I actually carry several different types of my favorite pens and a small set of colored pencils. This works great for carrying my supplied around with my planner!
