Great product.
"I really like the unflavored Collage. I add it to my yogurt. Only complaint, the lid is SO HARD TO OPEN the first time. I'm not sure if the glue from the liner is sticking to the lid. I have to ask my husband to open them (I never used to), and this last one, he had to put it on a vice to open it, and he's more brawn than brain."
