This thread works great with my Brother SE625 (same as the SE600). I haven't had any breakage with it so far, and it comes with a great variety of colors. I wish there was a spool of teal in the selection, but I won't dock any for that since it's clear what colors the pack comes with. It also came with some nice extras: stabilizer (tear away, and not good for floating but worked fine otherwise), bobbins (both prewound and empty, which my machine did not like at all and will not use), and thread nets. In the attached photo, I used simthread for the gold details and the eye/jewel.

quite like this thread, it has really lovely shine. I use this for machine embroidery designs. I have had no issues with it. I have recommended it to many people. This pack has a variety of shades from light to dark including greys. I think this is a real plus when choosing just the right colours. I appreciate the gifts that came with my package. You can never have enough bobbins & sleeves & stabilizer. It also came very quickly which is always a plus.Having a thread chart with true colours is a bonus. The only reason for the 4 is because you need an elastic to wrap it so it won't unravel.

I found the yarn to be good quality. The package comes with 40 colours. I like that a 63 brother colour chart was included and the 40 thread in the package was marked with a bullet. The package also includes a piece of stabilizer so we can use the thread right away for projects. Each thread is 500m and the colour number is printed on the spool. 7 bobbins were included, two of them wound with black and white thread. Overall, I find this to be a good value to have a variety of different coloured embroidery thread to do different projects.
