If you purchase the jersey and/or NN from them, they would iron them on for Free.  If not, maybe RM10 per kit, varies from shop to shop.

any thin piece of cloth will do, i.e. handkerchief etc etc.  Alternatively, flip your kit inside out, and iron on the back of the namesets with 2 dots (max).  It would be fine afterwards.  The 'wrinkles' are due to folding not error in printing.  Once re-ironed, should be ok.
