This slim PVC cover has a clear pocket as its main feature. The cover name “Alettone” refers to the part of an aircraft’s wings called an aileron, due to the way the techo cover’s lid can similarly fold shut with a snap. The soft PVC material makes it light and comfortable to carry, while the subdued color scheme gives it a sense of elegance. It closes with a snap button and has a design that fits any user in any setting. Foil-pressed in gold is the thought-provoking message, “Writing by hand is like sending your mind on a journey.”







The flap uses a navy-colored material with a slight texture to give it a feel similar to leather.







The clear pocket on the cover exterior can store tickets or your favorite stickers, or other tools like sticky notes or rulers.







The inner left part of the cover includes a clear pocket that can store cards, while the flap above that can be tucked into your techo and used as a bookmark.







The inner right pocket can fit postcards or tickets, and the pen hook can hold a pen by its clip.
