Does this product contain Erythritol?

The packets only list silica, but I don't know if silica is another name for Erythritol

Do the boxes that arrive look like the box pictured?

No, packaging has changed, or it is a different substitute fake. Mine came in a different package than I was used to. I ordered 3 boxes, with 2.5 oz in each box, what came was 3 boxes of 2 oz per box. The new fake stuff also contains silica which was not in the ingredients in old boxes, and is not listed in the ingredients of the pictures of what they are selling. This is a bait and switch. Oh and by the way, there are not refunds or returns. This company should be pulled off Amazon.

what is the expiration date?

sorry never looked at it but used for a yr anyway

This says 2 boxes-is it 2 boxes with total of 140 packets?

Yes the total is 140 (70 per box). I also bought the liquid SweetLeaf which works out well since I can control the actual amount of sweetness in my tea and take the packets with me to restaurants
