Tube snack 

Any type of snack that is contained in a tube, making them easy to store and transport.

Pringles. Or equivalent. If you travel, finding your favourite munchies can be tough. Regular bags of chips don't travel well. Tube snacks solve this problem.

Hey babe, grabs some tube snacks for the trip.
