No missing pieces. After working the puzzle all pieces are immediately bagged. This puzzle has NO BOX, which makes it especially great for adding to a bundle of puzzles, even larger (1500+) puzzles (see note below). Five pound weight limit for puzzle bundles still applies, and I will check the weight of individual bundles. 1000pc puzzle **Please Note** Due to shipping weight limits, I can bundle no more than 2 puzzles greater than 1500 pieces OR 3 puzzles of 1000 pieces or less. Three larger (1500+) puzzles can be shipped together if at least one box is not included. If you prefer this option, please include this in comments on your bundle.
