Review on πŸ§ͺ Affordable Zener UNMARKED Testing: Cost-Effective Solutions for Accurate Measurements by Duane Mann

Revainrating 5 out of 5

Really nice set of cards

I like them a lot! I am satisfied with the size of the business card. IMHO they are well made. And I love the design on the back of the cards. The design is way better than any other deck I've seen.

Pros
  • You save money compared to other unmarked cards on the market
Cons
  • Zero
