Closed 31 cm and all open 39 cm (adjustable with a plastic cord lock stopper and 2 silicone pearls at the end of the toggles)

You can make it a “breakaway” collar, if you take one of the pearls off the toggles.

Food grade silicone pearls are added to this EM collar.

The EM collar is only an addition to a regular dog collar. Do not attach a leash to it!

Colours will not fade!
