Plastic bin boxes
Your review: I recently moved my heating and air conditioning business and ordered about 200 of these, I have a lot of small parts that are a real pain to keep organized. These boxes were perfect for the job, they are very well built and look as good as bin boxes costing 4 times as much.
Pros: Looks great on the shelf, very well built, best price I could find.
Cons: Only come in black, and I didn't buy enough.
