Leaving a figure sealed is a collecting preference, not a guarantee that its condition will stay perfect. Before keeping a new purchase unopened, consider whether you can inspect its contents, meet any support deadlines and store it according to the manufacturer's guidance.
A box hides problems as well as the figure
An unopened package can conceal missing parts or shipping damage. Decide how you will verify the contents while the seller can still help. A shipping carton that looks undamaged does not establish that everything inside is complete.
If you bought the piece specifically as a sealed collectible, understand the tradeoff before ordering. Ask about the seller's condition description and support process rather than assuming you can discover a problem years later and receive a replacement.
Storage still matters
Good Smile's discussion of sticky figures describes plasticizer-related residue that can develop in stored PVC products. That is one reason “never opened” should not be treated as a universal preservation method. The exact material and instructions still matter.
Keep stored products away from unsuitable heat, dampness and direct sun, and inspect their condition periodically. Do not choose a storage location only because the boxes fit there. A garage, attic or windowsill can expose them to conditions you would avoid for an open display.
Choose for your own collection
If you want to enjoy the sculpt, opening it may serve your purpose better than preserving a seal. If packaging is part of what you collect, keep the inserts and box organized even after inspection. There is no need to make every item follow the same rule.
For a purchase from Super Saiyan Sphere, check the product and support information when it arrives. Keep your order record and packaging until you have resolved any questions about condition or contents.
