The design couldn't have been better for me, It's basically a childish good that adults love to use, I think that will help me as my possible customers get that little feel of nostalgia when they use it which is always good to have to help the buying process.
A buck and a half each, can't go wrong with a promotional tool that has the potential to send a positive message for your business and last a long time
For me and I'm sure I'm not on my own in this regard light-weight = thoughts of inferior quality. That's the impression i got when I opened my boxes anyway. I still used them and I feel they did better for me than I expected, but would like a little more weight to enhance the product feel.
