My desk & credenza came from Ballard Designs. One of the things I love about it is that you could pick the type of drawers you wanted for the credenza. Some of them have 4 drawers or you can get file drawers - it is nice because you can customize it to meet your needs. Just so you know, my desk is never this clean!
I have 3 of the Studio 3 cubbies for my Copic Markers & just love these so much. I like being able to have them easily accessible & sorted by color family. These were purchased at Studio3Solutions.
The white stackables on the far right is where I keep all my clear stamps. They are all in clear CD cases & I label each with a category so that I can find them! I bought the CD storage at Container Store but I don't think they carry this product any more. The organizer in the middle is by Making Memories Embellishment Center& I purchased it at Michael's with a coupon.
