• You mount them like an umbrella simply sliding the rod onto the umbrella holder of the flash, and then slip the fabric snoot over the front of the flash head and tighten the draw string.
• Unlike most other soft boxes, no assembly is involved…opens just like an umbrella
• Fits almost all flash units.
• For use only with electronc flash units, not for “Hot Lights”
• The Reflector Soft Box is a “reflector” style soft box.
• The light is bounced off of the silver interior in the umbrella and back through the diffusion panel.
