How to Preserve unused OPKs?

[Dazed]

Does anyone know of a way to preserve unsued Walgreens/Wafando OPKs? I bought them when I ran out of digi's and only used a few before I got what I believe to be a +. I only used 4 out of 20 and don't really want to see them go to waste. They are not individually wrapped and according to the instructions they need to be used withing 30days.

Thanks

I would put them in a food/freezer bag with like a sealable top.... or even in a tuberware plastic container with a lid to keep the air away from them and store in a dry out the sun place i.e wardrobe x
