I recently found these cute little contact lens cases while shopping online. If you want to keep your contact lenses from getting mixed up with someone else's or if you simply like cute stuff, then this might be a great product for you. They can get a bit expensive, depending on the retailer that you shop with---price can range from $4-9.
The frog case is actually from Forever21 and the other two cases are from Kikkerland (but you might want to shop around, other stores do carry them.) I personally think that they are really cute and they manage to put a smile on my face whenever I see them. What do you think?
