Using the Original Tick Key is straightforward. First, make sure to find a comfortable position. Place the key so the tick fits into the teardrop hole. Gently slide the key along your skin until the tick is trapped. Then, pull quickly in one direction to remove the tick. As for the colors, you'll get an assorted one, so don't expect a specific color. After use, you can simply wipe the tool with a clean cloth to keep it clean. Store it in a dry place, like your wallet or on a keychain, so it's always ready when you need it. If you have any questions during use, don't hesitate to reach out for more help.
