Alcohol Marker Pen Holder - Holds 16 pens! My wife asked me to create something that would hold 16 pens for when she is colouring so she knows what pens she is using, instead of the pens being put on the desk and taking up room. With this marker pen holder, it keeps the pens together so she knows exactly what she's using but it also doesn't take up a lot of room and it looks very smart!
