【HARDNESS RATING 2 TO 9】Each pen in this Mohs hardness test kit is assigned to a specific hardness level, covering ratings 2 through 9 for a total of 8 levels. During testing, there's no need to find the right angle on a single pen—just pick the pen that matches the hardness you want to test and scratch the above. The results are more straightforward and intuitive. 【DURABLE FORGED TEST TIPS】: Featuring high-hardness forged tips, this Mohs hardness tester delivers consistent scratching performance and enhanced durability for repeated use in field and laboratory environments. 【EVEN BEGINNERS CAN QUICKLY GET STARTED】Just pick up a testing pen and gently scratch the above of the object you're testing. Look to see whether it leaves a mark, and you'll get a good idea of the object's hardness. Renovation workers can check tile quality, and geology students can use it directly during field trips. 【COMPACT AND PORTABLE】The storage case for this Mohs hardness test pen set is compact—about the thickness of a smartphone and slightly wider than the palm of your hand. The lid snaps shut securely, so it won't pop open when jostled inside a backpack or toolbox. You can carry it anywhere, from a tile warehouse to a showroom. 【WIDE MATERIAL COMPATIBILITY】: Suitable for gemstones, jade, minerals, ceramic tiles, flooring materials, glass, phone screens, concrete, and geological specimens, this mineral hardness test kit supports educational, laboratory, and inspection applications.
