Dear Sir/ Madam:We are pleased to introduce Quarks and Topola puzzle products. In the attached brochures, you can find similarities between these puzzles and Rubik’s cube. But unlike Rubik’s cube, they are detachable hollow globs designed and produced by our company based on a new invention called Sliding Shell Mechanism. We primarily sell these products through Toy and Gift stores as well as distribution companies. The suggested retail price is $14.98 for Quarks and $9.98 for Topola and our selling prices varies between 25% and 75% of those prices depending to the quantities ordered. For more information please visit our website at http://www.fourieridea.com and feel free to contact us about any questions or interest.Best Regards Fourier Idea Inc Marketing Manager SHAHLA VATANNIA925-997-1295
