Biome in order to cut down on the plastic wrap.
They arrived in the post today, and so far look pretty good. You secure the wraps with velcro, which keeps everything together nicely, and the fabric is breathable which stops bacteria from breeding. Once used you simply handwash in cold water, then use over and over again.
So that's one more school task checked off the list. All I have to do now (besides put labels on everything) is to figure out how to stop my heart breaking as she waves me goodbye from the classroom door and I'll be fine.
