- Safety Features: Look for retractable tips or single-use designs. These cut the risk of needle injuries.
- Compatibility: Check if the needle fits your device. Universal Fit options work with most pens or tools.
- Material & Durability: Stainless steel lasts longer. Silicone-free or chloride-free options avoid irritation.
