Product Description Product Reviews Let the dice decide! This 20-sided die is designed by Lynda Mills and manufactured by our friends at Q-Workshop. It is based on the same design as our popular D20 Crits or Fails coin range. Lynda has adjusted the art so that the numbers are clear and legible. The D20 is 19mm diameter. © 2018 Campaign Coins Write a Review Write a Review × D20 Crits or Fails die Rating * Select Rating 1 star (worst) 2 stars 3 stars (average) 4 stars 5 stars (best) Name Email * Review Subject * Comments * 5 Great buy Posted by Malcolm on 13th Jun 2018 Campaign Coins and Q Workshop?
