Avoid kits made from low-quality metals like nickel-plated steel or brass, as these can lead to redness, itching, or even infections. Always check the product for certifications such as ISO 13485 or ASTM F138, which confirm the metal’s medical-grade quality. Next, consider the size progression. A good BB37 kit should include multiple sizes, typically ranging from 1.2mm to 20mm, allowing for gradual stretching. The key to safe stretching is patiencenever force a larger size into a piercing that hasn’t fully adapted. Most reputable kits on AliExpress offer a step-by-step progression, such as 1.2mm → 2mm → 3mm → 4mm → 6mm → 8mm → 10mm → 12mm → 16mm → 20mm.

These designs can enhance your personal style, but ensure they don’t compromise the structural integrity of the piece. Avoid overly bulky or sharp designs if you plan to wear them for extended periods. Finally, check customer reviews and seller ratings on AliExpress. High-rated sellers with detailed photos, clear size charts, and responsive customer service are more likely to provide reliable products. Look for feedback on real-world performancedid the jewelry cause irritation? Was the size accurate? Did it arrive on time? These insights can help you avoid common pitfalls.
