This is an LED squid jig that automatically flashes when it enters the water. It is 75mm in size and weighs approximately 8g. There is a light-emitting unit behind the 3D eyes. To prevent unnecessary flashing, the terminals are painted with red protective paint, but lightly sanding them will increase the sensitivity and make them start flashing. Each one will be shipped in its own case. If you would like to purchase multiple items, please let me know. Discounts are available for multiple items or combined purchases with other products. Thank you. #FishingTackleForSale
