I ordered the refill because I had thought I messed up the one that came with my machine, somehow it got tangled up and I cut it and I freaked out. The cartridge came super fast, but by then I had figured out how to repair the original one. So now I have an extra refill, but that's just great because I love my sticker maker, so the more the merrier.
It is a shame they have taken this product off the market so I was very happy that Scrapbook.com had some still in stock so I can still use my Xyron 500. Before I have to put it on the dump heap.
