Where to buy "Fresh Scents" sachets in Paris, France?

I will be visiting Paris soon and I was wondering if anyone could help me find these beautifully scented sachets for refreshing the rooms in a house. A friend of mine bought them in Paris a couple of years ago, but she can't remember where exactly she found them there. They are made in USA, but their website doesn't mention any stores in Europe which are authorized resellers or something like that. My friend discovered them by accident, she was walking across town and just saw them in a random store somewhere. This is the link to see exactly what product this is, so any help would be appreciated.

There are no "authorised resellers" listed as such in France. Individual retailers who want to sell them order them centrally.

They are likely to be found in shops that sell decorative goods for interiors, or sell a miscellany of presents, dress jewellery, ornaments, perfumed candles, etc...
In France shopkeepers generally tend to sell sachets made in France since the French are the world experts in scented goods and perfumes, rather than buying in imported goods, so shops that sell the brand you are looking for are likely to be few and far between, I am afraid.
Your post is marked as being from the USA and I have seen them in various shops there in different states. 
You could easily buy them on the net. Amazon sells them
They are retailed in the UK under the name Willowbrook fresh scents.

I agree with 1, the product you'd like to buy is made in USA, it'd be cheaper to buy it on Internet than in Paris. In Paris you'll find that kind of products at the main street of Saint Louis island or at the Latin Quarter, very touristic places.

You could buy some French, natural lavender to perfume towels etc.

You may want to try ''Monoprix'' on the Champs Elysées or any Department Store such as "Galeries Lafayette"...
