I bought a supposedly authentic Beauty Blender on eBay (all the packaging, etc appeared to be the real deal) but when I wet it to use it this morning, a white foam (like soap suds) came out. I kept squeezing it under running water but the foam kept coming. Is this normal for a new Beauty Blender? I've never used this type of sponge before. I'm suspecting they sent me a used one, even though it looked perfectly new!
