Love the look of these contraptions . . .but not so sure they work! It operates based on two separate wooden boards that clamped together and it is solely on pressure to flatten neckties. I think it might work great on silk ties. I love to display this piece in a man’s bedroom or his study. People always ask what is that used for? This would be a great gift with a new tie enclosed. It is from the 1920’s – 1930’s. A piece of history that is affordable.
