A Bathing Tiger Camo Sling Bag
It's not exactly a 'Bag of Holding' and nor is a $200 backpack imported from Japan, but it's PERFECT for:
carrying your gear to the academy
transporting small mammals
holding your lightsaber and a thermal detonator
raiding a dragon's lair
After purchase, please send photo of lightsaber and/or dragon's lair raid.
