I am very pleased with this Macarons-baking mat and can me the negative criticism of a customer who has first made me suspicious, and not connect. The baking mat is made of very smooth, completely odor-free silicone and leaves nothing to be desired. The piping bag (24 pieces (!) Are supplied free) do not stick together, can be separated very simply, are much more stable than typical plastic bag. On the mat or on the individual circles you see "non-stick surfaces," facilitate the work, although silicone basically not liable anyway. In addition, a small Rezeptheftlein is attached, so you can start right away. Really great, it makes enormous fun and our guests and friends will be fully beigeistert to taste pastry as in a Parisian patisserie!
