if you know what is to make French macaron cookie you know what I mean by writing this review. this cookies bit nasty so to make them amazingly good you have to dance and sing songs to God and or....buy one of this mats! extremely helpful for every dry pastry (cookies, eclairs etc) no stick even no any crumb! easy to clean, easy to store ( just roll up and use rubber band) no additional smell and its food grade silicone which do NOT POISON your food! I have a very good times with this mats ( I have 4 of them as I am a baker and cook a lot) and recommend you to have an easy good times with this mat as well!
