    Objects are smaller than they appear
    Color: 20 Pack
    I bought these to donate to a dog program at work. I was so disappointed when I opened the box and saw that they were so small. I hate when the adds make items look larger than they actually are. On the flip side, this would be perfect if you have small dogs.
