A collaboration with our friends at http://synergastirion.tumblr.com/ who designed the beautiful font for our custom made open/closed sign for our shops. (The sign is in greek for those wondering)Print the 3 files and glue them together to create your own ΑΝΟΙΚΤΟΝ-ΚΛΕΙΣΤΟΝ sign for your store or lab.Enjoy and open your lab for work! (and close it sometimes too..)
