This is a sun rendered oil made exclusively from pure fat of chanel catfish. No heads, skin, guts, or meat in this. Pure fat only. It will start to gel up at temps in the 60's but does not freeze solid. A true dark oil. Set out in the sun and it will return to a fine dark oil second to none. It has the smell of sweet pressed fish oil in the container but once removed it smells like fresh fish. This is the oil we use in formulation or straight as the lure. Super attractive to all animals. It takes many pounds of catfish to get enough fat to make a quantity of this oil! QUANTITIES LIMITED.
