I got my hands on in injector in a buy for a slim. It was a throw in but its in great condition and i wanna try it out but I dont feel like buying a pack of blades to test since they go for like $5-6 for a pack of 7 and $18 for a back of 28. So im asking if anyone has a single spare blade they are willing to sell or trade so I can try it out and see if i like it.
