So are you enjoying having your pet in the fancy play pen you got but annoyed by the scratch marks it leaves on the floor? We have the solution for you! Be it for home, training, dog show, breeding / whelping or dog show. These anti-scratch feet in black fit perfectly in a wire metal exercise playpen (like the famous dog / puppy / bunny / rabbit MidWest as seen in the photo). They are sturdy and don't come-off easily so your pet and floors will be safe! With the new updated and improved design, we added an internal notch to click and hold them tight in place. We also added 4 holes so an optional zip tie can be added and looped around for additional security so they can't be unintentionally taken off. We provide the zip ties with the order. They fit x-pens where the horizontal bottom wire is 0.14" (3.7 mm) and the vertical smaller wire is 0.12" (3 mm). These are crafted from PLA, a hard bio-plastic that is eco-friendly & sustainable, on a 3D printer so they are lightweight, waterproof and won't rust or peel, especially with pets, dogs, puppies, bunnies and rabbits. You will receive: - 16 anti-scratch floor feet in black PLA (hard bio-plastic) for wire metal pet playpen kennel (most playpens have 8 panels, so we are providing 2 feet per panel) - 20 zip ties (16 are needed, 4 are extra) This is made to order in the USA in my home in Woodinville, a small city near Seattle in Washington state. This takes 5 hours to print! Please reach out if you have any questions or if you would like customization. Lines and marks on the item: 3D printing carefully lays material line by line to form layers; these lines need to start and end, which causes a mark and is part of the normal process. It's similar to a fabric art, where there's a beautiful front and a back where the seams and contour lines show. Each 3D printed part is unique and made to order which will result in no two items being exactly the same.
