To our knowledge, there is no importer of organic silk comforters and organic silk bed linen in France. Unfortunately, many unscrupulous sellers abuse the term to ride the wave of organic.
In reality, sericulture is ecological because the silkworms feed exclusively on untreated mulberry leaves. Silk quilts are therefore natural but without an official organic label, we cannot talk about organic silk quilts.
The best way to be sure that the product is not harmful is to look for a label such as the Oeko Tex 100 standard which guarantees a product without undesirable substances.
