Alpine SleepDeep earplugs (Pt Richmond)

A slightly out-of-the-ordinary request: I bought this box of 3 earplugs from CVS. The box contains multi sizes to fit your ear. These work very well for me! I need the large size. I was thinking that if anyone else uses these, and actually needs the small or medium size, I would gladly exchange that size of mine for a large size of yours. They obviously have not been used. Thanks!
