Ks-Tek Sterilized Empty Vial with Self-Healing Infusion Port with Aluminum Plastic Cap Sterile Package (1ml, Clear, 10)

you can't really use them efficiently. I tried using them for material for injection like weight loss medication, but they are not high quality. don't get me wrong, they do the job if you're a doctor like me, but I wouldn't recommend them.

Ótimo, veio cada um em uma embalagem. Que pena que na achei aqui em João Pessoa. A entrega foi rápida, mesmo vindo de fora. Super recomendo.

A bit hard to removed the blue cap but otherwise great. Individually wrapped for sterility. Good product.

I use these to empty my injection medication into and divide it into thirds (used with a syringe) and these work great. They are a great quality and seal perfectly.

I use these for my GLP1 injections, I inject into the vial, add some bacteriostatic water and then voila, divide it into three injections. All of the vials arrived overseas unbroken and ready to use. Each vial was individually wrapped. No leakage. The only complaint I have is that there is no re-usable lid for storage. Minor thing, but work without.
