Lion Insta-Cover Ring Binder Easel, 1.5 Inches Ring, 1 Binder Easel (40009)

Can the item be used vertically as well?

where do I get refill pockets & spine labels for this item and can it take 80 refill pockets

Does it fold down for easy carying with other flat documents? I.e. how bulky is it for transport?

Is there velcro that secures the stand when in display easel mode? I will use it on a dance floor and it will need to be stable.
