Review on PUPTECK 12 Pack Soft Nylon Puppy ID Collar: Adjustable, Breakaway & Whelping Litter Collars with Record Keeping Charts by Jennifer Clark

I ordered these for a new litter of Scotty/Yorky puppies. At 6 weeks they are finally big enough to wear. They are well made, sturdy, nice nylon and the hardware feels nice. Time will tell how much of this plastic is. Large selection of colors. Heavy enough that brothers chewing each other's collars won't damage the nylon. They're easy to set up. The only problem we had was opening them. Hard plastic closure. There are no instructions anywhere in the packaging, and nothing is obvious by looking at them. It took me and my centers an eternity to open them. You press on the flat top of the latch, but you have to press VERY hard in the right place while pulling the latch for it to work. It will be interesting to see how difficult it will be for them to get off the squirming puppies and how long the clasps hold up under such heavy pressure. I definitely recommended them, but some opening instructions would be nice, along with a statement to press FIRMLY.
