Anisapo Knuckle-n Dog Leg Supporter, Size M, Used

I purchased this to support my dog's hind legs, but I either got the wrong size or couldn't attach it properly, so my dog barely walked and I stopped using it after two tries.
I hope it can be useful for someone else's dog.

I only used one for a single leg that needed support.
The one with the size tag on the back was not used. (See photo 2)

There are no noticeable scratches or stains, but the one that was used has some pilling due to the strong velcro and having been hand-washed. (See photos 5 & 6)
Please check the photos for the condition of the item.

The bag the product came in is wrinkled, so I will cut out the part with the product name and photos and include it. The instruction manual is also a bit wrinkled, but I will include it as well.

I have removed as much of the fuzzy hair attached to the velcro as possible, but please understand that this is a used item with signs of wear. Thank you.
