I was really impressed as soon as I got this collar out of the box. It's good leather on the outside, with a comfortable inner ring of padding on the inside. I was worried that, as with some cheaper collars, the hard outside leather might rub against her skin. But this didn't happen and she says that it's the most comfortable collar she's ever worn!
The attachment ring is sturdy and not just an afterthought; it comes in handy when we're playing with cuffs and leads as it can fit at least three attachments at once.
All-in-all, this is a great collar. It's not too intimidating or restricting for beginners and is comfortable enough to wear all the time. Even so, the D-ring is sturdy and very restraining.
