Candy with a logo on it, a letter opener in a digital world, a one size fits all t-shirt? These items are not often useful to consumers and admittedly could be a bit silly. There is no one size fits all, and a letter opener is a bit of a relic. If, however, you are wanting to invest in promotional products to use at a trade show or to give away during presentations, we have done some research for you! The following information can guide in helping to make a useful investment on a product that your clients will actually use, that can lead to a sale down the road, and keep you away from spending money on items that will end up in the trash.
