Is it possible to get rid of wrinkles on clothes after 2 years of being folded and packed tightly into a small, airless space?

Ok Ill be real with you, I want to buy an anime body pillow. However my parents are very religious and will most likely burn and or throw it away despite me spending $150 on it. Ill be moving away to college in June of 2018, but until then I plan to hide the pillow case in a small aluminum box with a lock on it and Ill keep the key around my neck until Im ready to open it. What I want to know is will it get permanent wrinkles if I keep it in there for 2 years? If so, are there any steps I can take to prevent wrinkling like maybe putting it in a wrinkle releasing dryer cycle once a week? Thanks
