The bag had to be <strong>practical and certified for contact with food.<\/strong>  <\/p>\n\n<h3 class=\"wp-block-heading\"><strong>Project<\/strong><\/h3>\n\n<p>The selection process took the form of an agency competition. The client approached several suppliers with a conceptual brief and expected them to demonstrate their own creativity and ability to develop the design into a fully-fledged product.<br\/>Key parameters: <\/p>\n\n<ul class=\"wp-block-list\">\n<li>attractive design for children<br\/><\/li>\n\n\n\n<li>exactly specified dimensions<br\/><\/li>\n\n\n\n<li>production in <strong>tens of thousands of pieces<\/strong><strong><br\/><\/strong><\/li>\n\n\n\n<li>use of <strong>certified materials for direct contact with food<\/strong><strong><br\/><\/strong><\/li>\n\n\n\n<li>Variability for <strong>different language versions and markets (CZ\/SK)<\/strong><strong><br\/><\/strong><\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\"><strong>Assignment<\/strong><\/h3>\n\n<p>The customer wanted <strong>practical snack packaging<\/strong>, not a toy.

The client&#8217;s original graphics had some flaws\u2014for example, the Martian character had no legs.
