We were instructed that students will not be permitted to put ANY decals directly on the devices, removable or otherwise. They are welcome to purchase a plastic cover from Amazon or ebay and place any decal on the cover, but will not be permitted to place anything directly on the device. If you have already purchased a decal for your device and would like a refund, please let me know. Even if I you have already received the decals, I will happily refund your money due to the confusion. I am happy to make a decal for anyone who would like to place them on a cover, but please know that they may not place the decal directly on the device.
