Here is the website for Halti collars: http://haltidogcollar.com/ This is brand new, never used, never even removed from the packaging. I ordered the wrong stinking size! I paid over $25 including shipping, but I see they are much less now, so I'm asking just $15, which includes shipping via USPS regular mail. The collar is red. PayPal only auction - payment due immediately upon purchase. Thanks for looking!
