The exterior of our Custom Graduation Diploma Tube is coloured imprinted or textured leatherette. The tube has a very smooth surface that makes it quite comfortable to grasp. There are eight tube colours to pick from, and you will find one that you like. The tube measures 32cm in length and 5cm in diameter, and it fits an A4 diploma perfectly. The logo and text could be foiled in gold or silver on the tube.
