Please see the self-introduction. The Olympic Thunderbird "Trout" series features all SiC guides that are as hard as diamonds and have excellent smoothness to prevent line damage, cork grips made of natural cork that become more comfortable to hold with use, and woven cross carbon that enhances strength and operability while creating the unique aesthetic of carbon. This series includes a high-sensitivity action series that caters to demanding situations from managed fishing areas to native trout, and a practical model series with long casting distance and powerful action for targeting large fish in lakes and main rivers. Please refrain from purchasing if you are concerned, as this is not a new, unused item.
