I don't think the unboxing can be accepted. These are the official rules-
1. At the start of the unboxing the box (or bag) should not have already been opened. This includes opening and resealing. It must be in the exact same condition it arrived in.
2. Should the parcel arrive in a damaged state then this may be used to the advantage of the unboxer if he / she wishes. However should the damage be so great that the box would no longer be considered suitable for purpose then the unboxing is deemed void.
3. Bubble wrap and other material used in it's transportation is deemed to be part of the box and must be fully removed.
4. Any packaging that the puzzle is normally supplied in (printed boxes, blister pack etc) counts as part of the puzzle and does not have to be removed.
5. The unboxing starts and finishes with both hands flat on the surface to be used or a timer. Hands must be empty at the start of the unboxing.
