Sterile Empty Vials with Self Healing Injection Port and Aluminum Plastic Cap,Sterile Package (50ml Clear 6PCS)

These vials are as described and easy to use. I would recommend and repurchase.

For anyone worried about that or actually having a problem try this. After you've flipped the top off just push it right back down. Maybe give it a spin and push it down again if you're really concerned.That will push all the metal down tight. No more sharp ends.

Works great for separating doses of once a week meds!!

Took 2 weeks longer then promised..don't know who's fault..very happy with product!

Some liquid got stuck around the rubber and couldn’t get it out.

difficult to get the flip top off and sometimes the inner rubber comes with it, or the metal surrounding it gets bent and leaves you with slightly sharp and uneven surface. Otherwise it functioned fine.

Very narrow
