Lock & Lock Eco Food Storage Container 850ml 4 "Forward thinking!" P Thomson 12 January 2019 I've been recycling glass coffee jars for storage of coffee, tea, dried pulses etc., but they're harder to lift than plastic and less economical with space. These containers have the advantages of less weight, space-saving and protection of contents from light, also addressing environmental issue of over-use of plastic. 2 questions: A) can recycled materials, including plastic, be further recycled? B) will there be other sizes in future? If these really do exclude light, then they would be excellent for herb & spice storage - I can never see the point of glass storage there. A note from the team Thanks for your review. There aren't currently any plans to introduce more sizes, but we have the four sizes available at the moment. Most plastics, including this can only be recycled once.
