K and j magnetics is the best!! Order all kinds of n42 and n52 magnets all the time. I'm still having an issue with my 26650 4nine tho. Ordered from 88evape. Normally all their shit works great but not this. The battery wouldn't even fit right. If I closed the top all the way it would start firing so I ground the copper piece down on the delrin ring but oops neodymium loses its properties at 175 degrees so I got new magnets and still battery won't fit. Might drill out completely and glue magnet inside... anyway, anyone else have this issue with the 26650? And it's a flat top battery
