Everything has some mass and a volume.
No one can carry without limits without some extraordinary measure.
Wooden dice weighs about 10grams = 2 x 2 x 2 cubic cms
A longsword is about 1.5 kilograms; volume = blade (110 x 5 x 15) + (28 x 8 x 17.5) cubic cm2
Its clear the volume of the sword is way more then that of a dice.
So lets say a simple pouch can hold 15 cubic cm...
Clearly multiple dice will fit, but not a single longsword. With a normal dice bag, around 100 dices can be put in.
Then wat about some very high mass material, Osmium, which ways 0.18kg / cubic cm... Putting 100 dice in that bag will tear it.
Over-encumbered: carrying to much mass (based on factors) - slowing down movement to a halt
Over-burdened: carrying to much volume - causing clumsiness due to the sheer volume influencing every movement
