I am deeply impressed how you achieve six perfect deliveries in a row. My orders must be the toughest that you get, with many small pieces, divided over several models in one order. My last order had no less than 1539 pieces. Also, my requirements on tolerance are stringent, as my twisty puzzles should turn smoothly.
Not a single pieces has been misprinted and not a single piece has gone missing.
Well done! Compliments to the people of your production unit.
