I love this design, its a rainbow or arch!
I only have black ones so far.
These stand 3.75" tall by 9" wide the holders are 41.4 mm
The top stand can hold big spheres up to 2.75", the second holder can hold up to 2.16" sphere, the bottom holders can hold up to a 1.91" sphere.
I did include a picture with spheres on one so you could see how they are displayed! ***The spheres are all sold separately***
