Tools Design raise the anti-design of all tea lovers to good taste for the Danish brand Eva Solo. After all, this metal bag - in contrast to its paper, industrially filled counterparts - can be refilled again and again with your own tea creations, just as you like for one cup. Simply remove the bottom, fill in tea leaves (the more, the stronger!), close it and pour hot water over it in a cup! With its typical ribbon and tag - but here modernised from wire and silicone - the tea bag is safely pulled out of the cup as a smart tea egg by Eva Solo.
