Only discounts available for bulk purchases! Measured with a tape measure. These are approximate measurements. S size: Neck circumference 21cm, Chest 35cm, Length 25cm I tried it on, but the size didn't fit, so I haven't used it. It was a large size for a 1.7kg Toy Poodle ^_^ I'm also selling gray. You can get a 215 yen discount for bulk purchases. Please refrain from purchasing if you are particular about minor details, as this item has been stored by a regular person.
