When we develop a new puzzle design, there are often slightly imperfect puzzles left over as a result of our tests. These "Research and Development" puzzles are a great way to try our heirloom jigsaw puzzles at a deeply discounted price!
-All puzzles are guaranteed to have all pieces
-We ship them simply, without a puzzle box
-Only one insert is included - reference it for help, or keep it hidden and discover the puzzle as you put it together!
-The most common issues with these puzzles are images with a border showing on one or two sides, or a few pieces being stuck together
