Thank you for viewing. This is a set of 3 colors of rabbit zonker material, 2.5mm. ● Black: Approximately 20-23cm x 4 pieces ● Yellow: Approximately 20-23cm x 4 pieces ● Red系 (Red-based): Approximately 22-23cm x 4 pieces This material is extremely versatile, suitable for everything from main streams and lakes to salmon streamers. It's a convenient material; if you cut the fur and use it as the tail of a Woolly Bugger, it becomes a soft and well-moving tail material. The long fur also provides stable movement in the water, resulting in attractive flies. After purchase, it has been stored in a container box indoors, so I haven't observed any significant quality deterioration. However, there are some areas that have been used, and there may be some dirt or damage to the outer packaging. Please understand that this is a used item stored by a private individual, and refrain from purchasing if you are overly concerned about these details.
