Versatile set of 50 plastic collars, 3 sizes, is very practical, especially for those who care about small details of their appearance. Having three different sizes is probably one of the biggest advantages of this item as not all collars are the same size. As for the product itself, it seems to stay true to the brand - quality remains. If you have ever bought a shirt you will find that most of the time it comes with a corset. But while they come with a stay, it would be foolish to assume they are good. Most often they are extremely flimsy and do little to nothing to prevent your collar from being tampered with. This product offered by Quality Stays is actually durable and will keep your collar in place. I am deducting a star for one purpose: the box. While these are quality products and the box itself looks pretty good, it's not necessarily well designed. Your big ones stand out, your little ones stay hidden. Also, the lid is tight, which gives the impression that if I try too hard, I'll end up in a situation where all my stuff will fly around the room. All in all a very good product!
