A tumbler for consumption of beverage and food is prepared by removing the metal top from a standard aluminum can and fitting a thin plastic sleeve over the exterior side walls thereof. Said tumbler is reuseable, extremely strong and unbreakable, and has a glass-like feel. The can is easily replaced by slipping it out of the plastic sleeve and inserting a new can therein. The invention unexpectedly permits the reuse of empty, discarded aluminum cans but still allows recycling of the cans after being replaced in the plastic sleeve.
