This is a simple design IDC*Power harness from JULIUS-K9 (Julius K9). The color is red, and the size is Baby 1 (3XS). It's for very small dogs. I bought it when my puppy was young and tried to fit it, but it didn't seem to suit him, so I stored it without actually using it. The size no longer fits, so I'm selling it. The size guide from the manufacturer's website is as follows: - Chest circumference: 29 - 36cm - Weight: 0.8 - 3kg Free shipping, and I will ship quickly, so thank you for your interest.
