Review on Lab Biotech Hydrophilic Syringe of Optimized Diameter by Ricky Habbani

Appears to be of very high quality. They work fine. You have to push slowly through the material, but that's to be expected with a filter this fine. They fit perfectly with the luer lock syringes I have. They're not individually wrapped, but I'm not sure how sterile that makes them appear. Overall I would recommend.
