The baseball cube is the mainstream collector's choice for archival storage of Major League Baseballs. This baseball case features a built in stand to keep the ball straight so the autograph stays aligned front and center. It has two equal u-shaped plastic pieces that slide together to form a precision fit.

Note: Be aware of cheap imitations. Make sure there is a UV certification report on any UV Baseball Holder that you buy to be sure that it is in fact UV Protectant! Our holder is stamped "UV" on the bottom to designate "UV Protection".

Question: How do you know which of Pro-Mold's baseball cubes are UV protected and which ones are not? Both products look identical.

Answer: The UV protected baseball cube has "UV" stamped on the bottom of it.

Question: What is the difference between the 5 year and 25 year UV baseball holders from Pro-Mold?

Answer: The 5 year version is made out of a raw material called Polystyrene, whereas the 25 year is made out of a higher quality material called Acrylic. Both products have ultra violet (UV) ray inhibitors added to block out harmful UV rays. However, unlike Polystyrene, the Acrylic raw material naturally blocks out UV rays even without the UV inhibitor that we add during the manufacturing process, so once the UV inhibitor additive breaks down the baseball is still protected from harmful UV rays.

Please keep in mind the UV protection will only keep the signature from fading, and will NOT prevent the leather baseball's natural aging effect of turning yellow.

Question: How do I open these?

Answer: There are two equal u-shapped pieces that slide together. See this video on YouTube: Instructional Video
