My granddaughter has this kit and I can tell you that the bands are quite a bit larger than a regular grooming band and not as thick. I know that
toplinepet.com
now sells the latex free grooming bands along with others.
Amazon.com: Latex Free Dog Grooming Bands by... Amazon also has a good deal on the bands. They also sell the multi colored bands for the same price.
The bands in the kit mentioned here are OK but it does take quite a few more turns around the topknot to get them on. The smaller bands only require two or three turns at the most.
