Closed 53 cm and all open 64 cm (adjustable with a plastic cord lock stopper) You can make it a “breakaway” collar, if you take one of the paw beads off the toggles.

Acrylic (NO METAL) pearls are braided into this EM collar.

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

Disclaimer - due to wear and tear the acrylic pearls might fade or change colour with time.
