Here's how to make the most of your Katana Mastery T - shirt. First, when you wear it, you'll feel comfortable thanks to the removable tag. The shirt comes in various sizes from S to 4XL, so you can pick the perfect fit. When it's time to clean, simply put it in the washing machine on a cold setting, turn it inside out and wash with similar colors. Only use non - chlorine bleach if needed. After washing, hanging it to dry will keep it in great shape, but you can also tumble dry on cool or low heat. Just remember, using fabric softener might make the colors fade. And don't iron it or take it to the dry cleaner. Follow these tips, and your T - shirt will look good for a long time.
