If your preference is ground coffee vs. E.S.E. pods, this is a must have. The Domepod case allows you to prefill 3 domepods beforehand with the espresso coffee (and the exact grind) you prefer. Just pop them in the case and bring them along. The Domepod case fastens on all Handpresso accessories' straps: the Outdoor set & the Wild Domepod case. Your Domepod and Wild machine will always be together and ready to go!
