How to use: Just attach the Fever Slot Raise Buckle to your DX Desire Driver or other compatible role - play items as shown in the official Kamen Rider Geats scenes. Then, you're ready to transform into the Fever Boost Form and start your exciting role - playing. Note: Keep it away from water and high - temperature areas to avoid damage to the electronics. Don't pull or bend the buckle forcefully. Maintenance: Use a dry, soft cloth to wipe it gently if it gets dirty. Store it in a cool and dry place when not in use.
