Instead of carrying everything in the bag, I love just simply carrying the most necessity items with me. This is why I adore this pen case. With my favorite pens in the case, I can attach it to my planner so I don't have to shuffle through my bag to find my pencil case every time. The cute button ensures my pens will be securely placed in the case. This case is loved by both college student like myself or my sister who works in the company. This is an item I'd totally recommend to anybody!
