Review on π§ͺ Micro Essential Lab Polystyrene Dispenser - Enhanced Testing, Measuring, and Inspection Solution by Chris Long
Nice Basic Strips - good value for money
pH paper is good enough. Pretty accurate and good solid case/dispenser. When I first used it I thought it wouldn't work because the strips don't change color when placed in known acidic or alkaline solutions. It turns out that the first few inches of the opened strip were probably exposed to the air for too long during storage etc. No problems after that and fairly accurate pH results.
