The default box condition is “Minimal Shelf-Wear” unless there is a drop down option/menu. Here at Brickollector we want you to make an informed purchase so we have developed our own box condition grading system below. This way you can have an idea (with our best intentions) of what to expect when you receive your LEGO from us. We will pack your order to the best of our ability but occasionally LEGO boxes can get damaged from courier services.

Sometimes boxes may have price sticker or security sticker on them. They are NOT treated as "damaged" at Brickollector. We do not remove these in fear of causing damage to the box. Please note that we are not brave enough to classify boxes as perfect (even if we think they are) so we will only go as far as 9.5/10. If you are a box collector and want us to send you close up photos of the box we may be able to accommodate such requests on a case by case basis.

If seals have been broken due to Customs inspection we will describe the box condition as such. We also reduce the prices accordingly based on how much damage the box has sustained.
