As with other magical bags, this one appears to be a common cloth sack of about 2 feet by 4 feet size. The bag of holding opens into a nondimensional space, and its inside is larger than its outside dimensions. Regardless of what is put into this item, the bag always weighs a fixed amount. This weight, the bag's weight limit in contents, and its volume limit are determined by making a percentage roll and consulting the table below:
| D100 | Weight | Weight Limit |
Volume Limit |
|---|---|---|---|
| 01-30 | 15 lbs. | 250 lbs. | 30 cu. ft. |
| 31-70 | 15 lbs. | 500 lbs. | 70 cu. ft. |
| 71-90 | 35 lbs. | 1,000 lbs. | 150 cu. ft. |
| 91-00 | 60 lbs. | 1,500 lbs. | 250 cu. ft. |
If overloaded, or if sharp objects pierce it (from inside or outside), the bag will rupture and be ruined. The contents will be lost forever in the vortices of nilspace.
