Hi, I was able to buy the pink iridescent CCH! A very smart lady on this forum told me to use Collonil Waterstop Spray. I use it on all my light bags. Just be sure to use a light amount and follow the directions.I”m going back and forth about the blue iridescent CCH. I think it’s beautiful and will provide something special to my outfit. I wonder if it can be sprayed with a protectant.
