These 6.5’ advertising spheres are our smallest spheres capable of floating with helium. We recommend them for indoor use and they are excellent eye-catching signage for trade shows or special events. Constructed of 18mil PVC, they feature digitally printed logos and graphics to match the companies’ branding. An airtight valve enables them to be filled with helium or air and maintain their pressure even longer. These spheres took 3 weeks to complete.
