Please refer to the profile. This is a "3.5mm Tungsten Bead Head Egg Fly #12" effective when the water temperature is low in managed fishing areas, or when you want to quickly get to the bottom of a deep, fast-flowing river. The hook point is opened for easy hooking. The hook is a Maruto egg-specific barbless hook. There are various other colors besides those in the photos, so please choose 10 colors you want. (If not available, I will select them.) Please follow the rules when using them in managed fishing areas. Discounts are available for "bulk purchase requests," so please inquire. How about adding it to your fly rotation? Thank you for your consideration. #flyfishing #finishedfly #managedfishingfly #eggfly
