Oh, you are too young bloss!
Back in the oldern days sanitary towels didn't have a sticky strip, they had a loop at either end and had to be worn with a belt! They did look a bit like hamocks for Barbies! And they were thicky and bulky and seemed to made out of netting! Just what you wanted to feel good about yourself during your period!
I hasten to add I was too younge to have used these types of towels, but they were still around when my periods started!
