This appears to be a common tote bag about 14 inches by 14 inches in size. The tote bag of holding opens into a nondimensional space: its inside is larger than its outside dimensions. If a tote bag of holding is placed within a portable hole, a rift to the Astral Plane is torn in the space: tote bag and hole alike are sucked into the void and forever lost. If a portable hole is placed within a tote bag of holding, it opens a gate to the Astral Plane: the hole, the tote bag, and any creatures within a 10-foot radius are drawn there, destroying the portable hole and tote bag of holding in the process. Printed on a Natural tote bag.
