These are standard ATC/ATO fuses. They are excellent for their purpose. They are inexpensive and come in a pack of 25. I'm guessing they're made outside of the US because the finish and graphics on the fuses are a little questionable, but hey, there are 25 of these for less than $10. What else would you like to ask?
