Is this backpack big enough for school?

It measures about 44 cm tall and 30 cm wide, which is a standard school-backpack size. It fits books, folders and a laptop, and leaves room for a lunch bag or a jacket.

Will a laptop fit inside?

The height and width suit most 13- to 15-inch laptops. The listing does not describe a padded laptop sleeve, so add a separate case if you carry a laptop daily.

Is it an official Doctor Who product?

The design is built around the Tenth Doctor and the "allons-y" catchphrase. Check the labels and tags on arrival if official licensing matters to you.

Who is this backpack for?

It suits Tenth Doctor fans and Whovians who want a themed bag for school, travel or conventions. Shoppers who want a neutral everyday backpack will find the print too loud.

Does it work as a carry-on?

At 44 cm tall it is close to the typical cabin-bag limit on many airlines. Check your airline's size rules before relying on it as your only carry-on.
