Measuring your jar is simple. All you need is a ruler or caliper:
🧪 For CT Lids:
Flip the jar upside down
Measure across the outer edge of the jar opening
Match it to the correct CT size (usually labeled 38-400, 63-400, etc.)
🔧 For TW Lids:
Count the number of lugs on your jar (usually 3–6)

Q: Are Nakpunar lids dishwasher safe?
A: Our lids are food-grade and leakproof, but we recommend hand-washing lids to preserve the plastisol lining. Glass jars are dishwasher safe.
