2 individual pH strips packs were included in the box. Each pack has its own strips that was wrapped with aluminuim foil to prevent it from moisture in the air.
I have purchased both the pH meter and the pH strips. I tested them with the same fish water. The pH strips indicated the pH of the water between 6-7 while the pH meter gave a reading of 6.50. So, this pH strips work and was accurate with comparison.
