Looking at your pics I dont think you realised but its heat shrink, if you hold a lighter or sumit under it, it will shrink down and attach itself to the macro, looks uber pimp, had aload of the 1st batch ones sent out to me for free (cant remember why) still got most of them somewhere, might have to hunt it out.
just looked em up again apparantly all you need is a hairdryer to shrink them, dont really want a flame around your macro

As stated above around 3 days ago ColseyJust so you know guys this is heatshrink,the idea is to slip it over your macroline and then apply a little heat,use a hair dryer or heat gun on low setting and it 'shrinks' down and covers the macroline tightly like this
