I've bought a collar from the brand MASBRILL. To be honest, it's not particularly outstanding compared to others, but my dog seems very satisfied with it and has never shown any discomfort. So when I found out that they had a set on sale, I immediately bought it. The collar is the same as before, but the leash is a pleasant surprise with its extremely comfortable lining! The only drawback is that the length of the leash cannot be adjusted, but since I have a small to medium-sized dog, it doesn't affect me much.
