These delightful items were also known as "tie fillers".
They were used to help preserve the shape of Tootal Tebilized ties.
As you can see, they also contain information/advertising for Tootal ties, and laundry tips.
(This was, of course, long before the days of "garment care labels", and the information is a little vague by modern standards.)
They date from the 1930s to 1950s - there are minor differences of shape and colour printing, as you can see.
They all have plain backs apart from Style C, which has a yellow back.
Tie stiffeners were put inside the tie:
- to keep the shape of the tie when it was being pressed overnight in a "tie press".
- to help it dry "straight" after washing (if you have ever washed a Tootal tebilized tie, you will appreciate that this is quite a tricky operation)
- to help prevent "seam marks" on the tie while ironing.
