Ks-Tek Sterile Empty Vials with Self Healing Injection Port,with Aluminum Plastic Cap,Sterile Package (3ml Amber,10)

My daughter uses them for her semaglutide. They work very well for this. I would purchase for her again.

2 out of the 8 vials did not self heal/seal properly after 1 to 2 withdrawals. Popping off the caps also appeared to damage some of the aluminum top.

I needed to split up my semaglutide dose. I simply shot the pen into this sterile vial until hearing the 2nd click from the pen. I then could withdraw the needed amount from syringes for administration. Perfect!

This is exactly what I needed and expected. They do the job just right. Good value. Highly recommend

This worked perfectly for what we needed it for. Thank you.
