The only time they will be different than Joye, they will say it in the drop down...The Keimer Gold Band are Joye Type attys, but not Authentic Joye Tech attys...I put the names in the description for the times that I run out my normal 510 stock which is Joye Tech...I have been getting superior performance from the Gold Band attys and may be changing the stock soon if they come out with some more colors...Thanks
