CollarSafe's Brand Puppy ID Bands are Custom Designed & Hand Made in the USA with top quality hook and loop fastener. These SLIM bands are 3/8" in width and come in your choice of lengths. When determining your length PLEASE add or allow a minimum of 2" or more for overlap to fasten (the more overlap, the more secure collar will be). CollarSafe has been making these little Puppy ID Bands for over 10 years. CollarSafe NEVER uses the inexpensive imitation/generic material. CollarSafe Puppy Bands are reusable, flexible, self-gripping with a unique back-to-back fastening system. Bands wrap around and then the remaining band tip attaches back onto itself for a neat and secure closure without buckles or hardware. Just like humans, all pups are different and may be more sensitive to some products than others. All puppy products will not be appropriate/suitable for all breeds and/or situations. Any and all puppy products must be used with extreme care, continually monitored & adjusted, or discontinued accordingly to your specific breed and/or situation. Custom Designed and Hand Made in the USA by CollarSafe.
