I have a box full of reusable K-Cups that are compatible with Keurig machines. There are 36 packs of pink K-Cups which are compatible with 1.0 and 2.0 machines and much more. And there are 31 packs of black K-Cups that are compatible with 1.0 machines and come with a clip to make them compatible with 2.0 machines. Each pack has 4 K-Cups. The reason I cannot sell them online is because of slight damage on some of the packages. The product is brand new and unused. Dm me if you’re interested or want more information. Each pack is usually sold for around $10. More product details are below.
