Not as easy to get lost or stolen. And well protected. Sometimes only one chip placed in the center surrounded by filler. Keeps thieves from pocket size theft and doesn't get lost between the cracks. I have had a couple never reach me and it is frustrating especially when it's a rare and hard to get chip, like a pissycat a go go chip I've never seen another for sale that I paid $500 for and never got, wah so bummed.
