Using your Artisan Dekaranger Master License is a breeze. First, insert an ID card into the holder and then attach it to the Master License. You can switch between different ID cards to access the Judgement Mode and hear Toru Inada's voice. When not in use, store it in a cool and dry place to avoid damage. Clean it gently with a soft cloth if it gets dirty. Don't expose it to extreme temperatures or moisture. Have fun with your new collectible!
