I received the air fresheners that I ordered last week and I love them! I think they will be a great take-away to hand out at my portfolio show.
The company that I used to print them is Air Trends International (http://www.airtrendsinternational.com). They were super helpful; they sent me proofs so that I could approve how the design was laid out, they made scent recommendations based on my target audience, and they allowed me to place a small order (most other companies had a 100 piece minimum).
