IMPORTANT The ceramic paper attached to the art box can be cut to the bottom size and pulled inside the art box. Paper on the surface of the art box is non-flammable. It may burn by heat, but it does not burn out, so please do not remove it as is. When using art boxes, a single function microwave is the best choice. When using the multi-functional open range, please use the strong and weak switch. Please note that if the turntable detects weight by microcomputer repairment, you may not be able to use the radio output as much as you need to heat up your art box. Please do not use the microwave as food preparation products for hygiene. It is recommended that you have separate lenses for art boxes. When using it with food preparation, always wipe the inside of the microwave after using the art box.
