Using your Snouleaf's 'Wizard at Your Service' long - sleeve t - shirt is as easy as putting it on. Just choose the right size from S to 4XL that fits you well. When it comes to taking care of it, make sure to machine wash it in cold water, turning it inside out and washing with clothes of similar colors. Only use non - chlorine bleach if it gets really dirty. After washing, hanging it to dry is the best way to keep its shape and color. But if you're in a hurry, you can tumble dry it on cool or low heat. Remember, don't use fabric softener because it might make the colors fade. Also, stay away from ironing and dry cleaning to keep your t - shirt in top condition.
