Ks-Tek Sterile Empty Vials with Self Healing Injection Port,with Flip Off Aluminum Cap,Sterile Package (10ml,10)

Great Vials very well packed. so much cheaper then buying singles.

Amazing little kit!Great quality and the stickers are a great added bonus that others don’t supply!

Would have been better if lids weren't on

Fast delivery Great productOnly disadvantage lid does not fit back on otherwise perfect

great vials, packed and sealed in a sterile environment which is great! I only graded it at a 4/5 since it required some effort to just get the silicone stopper out of the empty vial without needing to snap/damage the metal band. This is purely cosmetic and isn't that big of a deal for personal use, but for commercial use I suggest maybe adding some sort of little plastic tool to open the vial (keeping the metal band and purple seal intact).

Just what I needed and arrived quickly
