You May Want to ask:
1,Do the mats slip or slide on a counter top?
They do not slip or slide at all. Very good mats.
2,Does the hot pad really smell bad? How to get rid of it？
Well.. I did't smell anything strange, the description notes that these pot holders are made of silicone, so I guess the smell might be this. To get rid of the smell, you can try to put them in boiling water for 2-3 hours or a salt and vinegar solution for 20 minutes. Then to air dry the hot pad, the smell will vanish.
3,Is this trivet mat can use as a drying holder for my hair tools in the hair salon?
Sure. It's safe for microwave, the normal temperature resistance is at -22F to 450F, much less for the drying holder. The convex and concave strips on the front surface enable the water draining more concentrated. I also use the silicone mat to hold high temperature pots or ovenware can insulate the heat without scalding myself
