When the dab session is on, small amounts of concentrate might splash from the nail and much of it comes straight on the table which obviously isn't desireable. When you make concentrates it's also an advantage if you can collect it on something else than parchment paper. For both of these reasons it's worth getting a mat to use as protection when dabbing and creating concentrates. These silicone mats are made for these exact reasons and are guaranteed to give you a better experience no matter how you handle your dabs.
