Pam, I ordered the disposable contact cases from my eye doctor in lot of 500 if I remember right - each one has 2 sides. I split the order with another person. WAY less expensive than buying them individually in Wal-mart etc. I put a piece of tape on the top to write the name of the pollen on. Easy to wash out and use over. Also, air tight. Last year I filmed on how to use them. I just need to sit down and edit it to make a video and upload it. They are pretty handy.
