They look like promo items. I got a yellow one from a Schick employee back in the 80's when they were marketing their answer to the Atra. I actually miss that cheap toiletry bag. It went everywhere with me and it managed to last for about 12 years.
Yeah I kinda figured it was a promo bag would be cool to find out which event though. Also yes its about the size were two tennis ball containers could fit or at least one and half. Thanks for all your responses.
