VIVI SKY Ninja Reusable Coffee Pod

I purchased these so that I can use my own grounded coffee instead of pre-packaged Kcups. I save a lot of money using these and the stainless reusable cups last longer, 2 years and counting. The reason I bought 2 packages (4 Kcups) is due to I can make specialty coffee for my company without rushing to clean up the used Kcup for another cup of coffee. Some people do not like flavored coffee, so I purchase in bulk regular Kcups, and use the reusable for specialty coffee. No flavor contamination.
