Why These Spacers Stand Out
• Precision Fit: Engineered to snugly fit 3 ml injection pen cartridges, preventing wobble or misalignment for a seamless injection every time.
• 3D Printed Excellence: Made with cutting-edge 3D printing technology, each spacer boasts flawless consistency and a lightweight design.
• Built to Last: Crafted from tough, high-quality PLA plastic that resists wear, ensuring reliability through countless uses.
• Color Your Way: Available in a rainbow of bold shades—pick your favorite or mix and match to add a splash of personality to your medical gear!
• Great Value: Get 10 spacers per pack, so you’re always prepared with spares at home or on the go.
Designed for 3ml injection pen cartridges used in reusable pen injectors, including pens that fit GLP-1 and insulin cartridges.
