We are not supposed to use normal cups and mugs outside of the staff room in case of spills etc and the potential risk to children.
But the school bought metal flasks with kids are not nice. The drinks taste metallic from them and the kids are not really very secure at all.
Any suggestions for a decent lidded drinking vessel that keeps the drink warm for a little while - in case get called away for a bit - and had a lid which stays on and doesn't leak. Oh and where your drink doesn't taste of metal or plastic.
Thanks
