You really shouldn't go for the lowest-priced needles. There are dependable and affordable options that set the standard for quality. From the orange color it looks like it could be a 25 gauge. I've run into needles from similar sources that had the wrong size printed on them.
I found this strange-looking needle right beside a normal one inside a recent box I bought. The packaging was ripped open on the back so I decided against using either one just to be safe. Only the best medical gear for me, right?
