Retropedia makes a lens for digital cameras from lenses from disposable cameras. They're supposed to give images a “retro feel.” I bought one (they're very inexpensive) but was not really impressed with the images I created with it. If I want images with lots of character and true retro feel, I prefer to use one of my vintage lenses.
Anyway… they keep sending me emails about being part of their affiliate program. I absolutely do not remember ever signing up for that, but whatever. It's just more email messages to ignore.
If you want to buy one of these lenses, why not use my affiliate link? https://www.retro-pia.com/MATTHEW08770
