Inaccurate description. Technically these are luer lock fittings, but are they just blunt tip tubing? Bought to attach to luer lock syringes to give my horse intramuscular injections. However, since there is no sharp beveled tip at the end, you cannot use it for injection. They are also non-sterile, packed together in a small paper box. I'm sure they're used for something, so someone will find them useful, but that something doesn't give an injection. To be honest I have no idea what they are…
