Farcellet d'herbes aromatiques

Actually I learned that this is Catalan, not French as I thought it was first.
I receieved some wonderful parcels last year and in one of them from my friend Monica in Spain were these beautiful herb parcels.

They are quite common in Spain as I understand, but I have never seen them before. I love the idea of different spices together wrapped in another spice. Exactly what herbs it contains is actually a secret but I think sage, thyme etc is hidden in there.
It has a wonderful smell.

I have actually not tried it yet, you are suppose to use it when you make stews which I haven't made for some time. But I'm getting so curious now that I will have to make it someday soon.

If anyone is familiar with these beauties, please tell me.
