Our exclusive baker's couche by BrotformDotCom is made of natural flax linen that have not been treated with any chemicals. Imported from France. Measures 26 x 35 inches. Finished seam on both sides so it will not fray over time. *****Important***** Do not wash your couche. A couche should never be washed. Hang and air dry after use, then roll and store it for future use. Because our couche is made of natural and untreated flax linen fabric, the odor you may experience is completely natural. It will not affect the aroma of your bread and it will dissipate in time. Do not bake in oven. A couche is used to proof the bread. It can not withstand the heat. Attention Sellers: This ASIN is for the BrotformDotCom® branded couche. Please do not add your generic or other branded products here as they are not the same products and have a different UPC and quality standard. If you have any questions, please contact Green Magnolia. Thank you.
