Thank you for viewing! *Please check my profile before purchasing.* This product is the "TTFP Anti-Bark Collar Mint Green." *The blue collar is not included.* I purchased this on Amazon. It was effective for my 4-year-old dog, but it didn't work for my 8-year-old dog, so I am selling it. I have only used it once. Instant purchase is OK! To reduce shipping costs, I will fold the outer box for packaging and ship via Yuu Yuu Mercari. I do not offer holds or price negotiations. Please purchase only if you agree to the above.
