I have been ordering from 4Imprint for several years now. The 15x12 Convention Bag is of very high quality. I have ordered it on more than one occasion. It is of ample size for a convention, tradeshow or other events, and the quality is quite durable for the price. I also have to say that the graphics and verbiage I included to be printed on the bag printed very clearly. I really do like ordering from 4Imprint, and I am always satisfied with the finished product.
