Would anyone be able to direct me to a place to purchase old cases for Gillette razors? I'd like to find one for my slim adjustable and for the four razors I picked today at a flea market. Two of them are black adjustables with short handles. One of them is a black adjustable with a long handle. The final one is a long handle blue razor. I believe it's called the Lady and it has long stars towards the head. Unfortunately, they did not come with cases. I did a search on Ebay but found nothing. I would appreciate any direction. Thank you.
