I have used this product multiple times.  In fact, I purchased four tubs of the gold and silver luster dust (2 each) five years ago and I am JUST NOW running out!  I use this stuff to gild all sorts of things for Renaissance themed banquets - including gilding an entire roast duck and then, using vodka, painting filigree designs onto it!  The clients thought it was prop food it looked so beautiful.  I can't recommend this stuff enough!

I must say that my dog and all at the dog park LOVE these treats. Even the very fussy boxer sniffs at my pocket waiting for them. The sizes are quite variable which is ok.  The product arrived with no protective covering on either the outside of the tub or under the lid which bothered me a bit (not sure if they had been open, returned by someone, then sent to us) so that is why I rated 3 stars.  The amount of product for the price is great! I would most likely purchase again.
