Like all things produced by Strict Leather, this collar exhibits excellent workmanship and top notch materials.While you canʻt tell from the illustration, the entire inside layer of the leather collar is smooth. No rivets or grommets pass through it to scratch the wearerʻs neck. And yes, I do mean layer since the collar is constructed from three layers of leather stitched together. Note that the collar has three D rings not just two as shown by the photo.On the negative side, the hardware seems lighter than the hardware on the matching Premium Wrist and Ankle Cuffs. The D rings are thinner and the buckle doesnʻt seem as stout, even though its the same design. This is probably not an issue since these fittings wonʻt bear the stress that the cuff fittings do. But still, it would be nicer if they matched.One last thing, that I canʻt fault them for since its clearly in the description, this collar is WIDE!!! I didnʻt realize how wide 2 1/2" was until I buckled it onto my submissive. It virtually becomes a posture collar holding her neck and head upright. Again, not a fault, but something you should measure and think about before ordering. The smooth rolled edges of the leather keep the collar comfortable even with its width.On a positive note, the width of the collar spreads any stress to the neck over a wider area and therefore is safer than thinner collars. I would definitely recommend this collar for anyone interested in pro-dom quality leather goods.
