Does anyone have a recommendation for a refillable Nespresso Pod? My mom recently retired and would like to travel with her machine (inspired by Swissaire here). She will be going on a few longer trips that may not include larger cities where there is a Nespresso Boutique (or a Nespresso in that country) and carrying a large stack of sleeves might not be the best option for her.

I just bought her a Pixie Clips unit for her travels and am making a carrying case for it as the original Nespresso one is sold out.
