Three 1960s Hi-Style Hair Clip / Barrettes. The big one is 9.5cm long and 4.5cm tall. The two smaller ones are 6cm long by 2.2cm tall. The last picture shows the backs - and the fixing mechanisms. They were made by Tip Top Products co, in the USA and have a little seal at the bottom claiming they are guaranteed by Good Housekeeping magazine. I have them in tortoiseshell, red or pink.
