Review on Vitamin D3 Free Calcium Supplement for Reptiles by Fluker's by Sabrina Jones

As many others have pointed out, mine also arrived with the lid unscrewed. I was lucky it was still on the tin but was very loose and leaked a bit. A few more nudges on delivery and I probably would have gotten an envelope full of powder. Even without a top seal, a simple piece of tape stuck to the lid during manufacture prevents it from unscrewing. It's a good value as I paid less than $1 for it but not much when it arrived empty.
