These products are super easy to use. Wear the T - shirts, tank tops, and hoodies as you would any regular clothing. Carry the tote bags to hold your daily essentials. Hang the posters on your wall to add a cool touch to your room, and use the home decor items to spruce up your living space. When it comes to maintenance, for clothing items, follow the washing instructions on the label. Usually, a gentle cycle with cold water is best. For posters and home decor, just keep them away from direct sunlight to prevent fading. Also, be careful not to scratch or damage the tote bags. Enjoy your unique 'Soul of the Katanas (Alt)' products!
