[PRE ORDER] ROSE CORAL/AZALEA HARNESS

O-ring: 3cm Outer diameter/ Inner diameter 2.2cm / Thickness 4mm]   ⚠️Note on usage * Wear it without the O-ring if your fur baby isn't a calm walker, and use the O-ring indoors so you can use it safely. * If the O-ring spring becomes loose depending on the frequency of use, be sure to replace it with a new ring.  (It is recommended to replace it once every six months if used daily) * For safety reasons, we use a thick ring. If the leash buckle is narrow, there's. a danger of it opening, so make sure to use a leash buckle big enough for the O-ring. * The O-ring enables you to adjust the length as shown below.
