This collar stay bottle is a must-have for any man who wants to add a touch of sophistication to his wardrobe. As my tests showed, the plastic collar bones are sturdy and easy to insert, making it a breeze to keep collars straight and crisp. The sleek design of the bottle makes it easy to toss in a suitcase or gym bag, making it perfect for the man on-the-go. The only downside is that the bottle is a bit on the small side, so it might need to be refilled frequently. Overall, a great addition to any fashion-focused man's accessory collection.
