A word of caution to anyone considering buying these: Read the ingredients first! I made the mistake of thinking they would be the same as the longer (Oberto brand) ones our local Costco used to sell, so I ordered up 10 bags to get the volume discount offered at the time. I knew something wasn't right as soon as I opened up the first bag and got a whiff. Then I read the ingredients and was shocked when I saw that they actually use pork hearts as the top ingredient. To eliminate any doubt, I tasted one.. we've been using them as expensive doggy treats ever since.

Ex Output:
Negative

I have purchased several herbs from Frontier which have been of good quality.  Thyme leaf is always one of the most difficult to purchase due to the likely chance of recieving more stem than leaf.  This thyme leaf purchase was of average to good quality.  I did have about 30-70%, stem to leaf cut in the package, so I was satified with the selection.  When I dry my own thyme leaf, I usually do about the same or a little less stem to leaf ratio for cooking use.  Stem of the thyme leaf are just as favorable as the leaf and can be used to cook with successfully.

Ex Output:
Positive

Delivery was on time but when I opened the product it was like the shelf life expired.  They were hard and chewy. I contacted the manufactur and they sent out a new box. I will be ordering direct from now on.
