【Masumasu Yarn】 Excellent for catching fish due to its predatory trigger effect! Plus, it's easy to tie! 【What is the Predatory Trigger Effect?】 The reason why Marabou streamers, which don't resemble anything in particular, catch fish using patterns like "Woolly Bugger," "N Special," "Kaga Bari," and "Marabou Leech," is hypothesized to be due to a shared "predatory trigger." This high-performance material attempts to unify that trigger. Furthermore, by incorporating simple tying techniques described as "girling," it has become a material that catches fish well, is easy to tie, and is highly durable. 【Masumasu Yarn】shows excellent results, and trout respond favorably in any situation, from tough conditions to high activity levels. It is suitable for all fishing methods, including retrieving in lakes, swinging in rivers, and marker fishing in managed fishing areas. The selection has expanded further with the ability to use it in conjunction with its strongly appealing sister product, 【Masuriki Yarn】. Please select 5 colors after purchase. Each color comes with two types of yarn with different properties (1m x 2 strands) per set. You will receive a set of 5 colors. You can tie about 80 flies in total, which is a great value compared to similar commercial products. 【Discount Service】When purchasing multiple sets, we will discount each additional set by 100 yen. Please request this through the "bulk purchase request" (please note that the discount will not be applied if you do not enter the amount). The description is based on the personal experiences (and feedback from repeat customers across Japan) gained through trial and error based on the hypothesis. We do not guarantee fishing results or fish reactions. As we are not a major manufacturer, there may be slight variations in color. Please consider the color names as a guide. Please refrain from purchasing if you are overly concerned about this. #FlyFishing #FlyTying #MarabouLeech #MontanaMarabou #GRunner #Aomidor #Shelter #SpeedFiber #Chenille #PelletDub #ChuzenjiLake #AshinokoLake #Marunuma #YunokoLake #HigashikoyaLake #AkanLake #KagaBari #Area #FlashScale #FlyMaterials #MasurikiMarabou #MarabouBodyMaterial #NSpecialTyingSet #Haruzemi #DryWakasagi #OkePira #Masumasuya
