2.25mm Herm Sprenger Prong Collar Extra Links Chrome Plated (3 pack)

Well made. Proper fit. Sort of easy to add or remove from existing collar which means it’s just right. Other links are either too easy & fall out of collar (releasing it) or points are too sharp. These have effective blunt prongs, not evil points! The idea is to remind the dog by making him briefly uncomfortable, not to wound him. I used to think prong collars were evil becuz I saw people misuse them. But my trainer educated me & they are wonderful tools.
