A method for opening a telescoping insulated box assembly, the method comprising:

• obtaining an inner box disposed within an interior cavity defined by a plurality of outer side walls of an outer box;
• grasping a portion of an access tab, the access tab overlapping adjacent outer sidewalls of the outer box and comprising a telescoping portion and a perforation, the access tab securing the inner box within the interior cavity of the outer box, an outer top edge of the outer box defining an opening to the interior cavity, the inner box positioned upside down within the interior cavity with an inner top edge of the inner box touching an outer bottom of the outer box, the telescoping portion of the access tab covering a portion of the outer top edge of the outer box and a corner of an inner bottom of the inner box;
• tearing the perforation and folding the telescoping portion of the access tab upwards to expose the corner;
• and
• removing the inner box from the interior cavity of the outer box to expose the interior cavity.

An assembly, comprising:

• an outer box comprising a plurality of walls comprising an inner wall portion and an outer wall portion extending from a top edge to a bottom of the outer box and defining an insulation cavity between the inner wall portion and the outer wall portion;
• a telescoping box within the outer box and comprising a plurality of walls comprising an inner telescoping wall portion and an outer telescoping wall portion and defining a telescoping insulation cavity extending to a bottom of the telescoping box between the inner telescoping wall portion and the outer telescoping wall portion, wherein the telescoping insulation cavity extends to the bottom of the outer box;
• and
• an access tab overlapping adjacent walls of the outer box and comprising a telescope covering portion configured to cover a corner of the telescoping box and a perforation configured to be torn to allow removal of the corner of the telescoping box from the access tab.
