What does needle gauge mean?
Gauge describes needle diameter. A higher gauge number indicates a finer needle, so 30G is finer than 29G. Gauge alone does not determine which product is appropriate for an individual.
How should I choose the barrel capacity?
Match the barrel capacity and U-100 calibration to the specification you have been instructed to use. Do not substitute a different capacity, gauge or needle length based only on this comparison.
Packs of 10 and 100
Packs of 10 can suit occasional reordering or checking a familiar specification before buying a larger quantity. Packs of 100 offer a larger supply. Availability differs by capacity, so check the product options before ordering.
