Sealed-air globes include the globe & inner bladder. For indoor use, the sealed air models come with a portable electric inflator/deflator which quickly inflates the globe in just a few minutes. Outdoor use generally requires our "Cold-air" models, which feature an internal blower. Cold-air globes are more expensive to rent or purchase, but they are immune to changes in temperature and barometric pressure.  They'll remain properly inflated as long as they have electric power. Our growing fleet of rental globes all feature the NASA digital Earth image complete with atmospheric cloudforms, available in a range of sizes. Other sizes and custom Globes are available.
