Hello - I hope it's OK to do a little market research here (if not please feel free to move to Marketplace). As a PE teacher who lost mobile phones and money in lessons (as they weren't labelled and were dumped in a biscuit tin), I created ZipSafe. ZipSafe bags are small cotton bags that students can put valuables in and write their names on them. I am keen to learn how departments deal with valuables - some do have a bag system whilst others just state to the students that valuables are there at their own risk and should be left at home. I set up ZipSafe really as a solution to my problem and wondered whether there would be a lot of demand for it nationally? The bags are made from Fairtrade, organic cotton. If anyone would like some free bags (pack of 10) then e-mail email@example.com with your school address. Would appreciate any thoughts and feedback.
