Normally, for a formal professional association type of business, they will go for some unique colour USB sticks such as black, white, silver colour which are widely used during business conference. While Funky style USB Keys is a more wise option in order to attract customers attention. It is always the best to ask our experienced sales before making your decision, because they are more familiar with the product, and definitely can find something that is what you want.
