Sumind has been making great spacer for years, thanks to a combination of clever design and high-end materials. It is great for those that need spacers to change their stem. They look like they are legit carbon fiber so that is good. They can raise and lower the position of your stem on the steerer tube, as long as your stem fits the steerer tube.

There are plenty of pieces included in a single package that provides more than enough for several bikes. They are carbon, so ultra light. It is good for it's intended purpose.
