It is very easy to adjust thanks to the four holes, the "Dual CF" is a dog collar made of nylon with a simple and basic design. The double strap it is made from ensures special comfort and strength, while the coated metal buckle makes the closure secure, adding at the same time a touch of elegance. The collar is available in classic white and also in bright colors such as purple, bright orange, and fluorescent green, where all collars have a black inner strip that creates a nice contrast with the other colors. The "Dual CF" is available in four sizes that vary in circumference (from 27 to 53 cm) and in strap width (15, 20, and 25 mm).
