Diamond lapping fluid has been developed to be used with these stones so they work at optimum efficiency. Do not use water with diamond stones as rust can form, degrading the stone over time. These stones can be used to flatten wet water stones and it is okay if they get wet, but with any diamond stone, they must be dried fully before putting away.
This bottle has an ingenious lid that clicks up and lets only a drop out at a time, just tap onto the stone. Use sparingly this bottle will last a very long time, as it is not necessary to flood the stone with lapping fluid.
