High quality with very fine particles
I’m really impressed with this CMS Magnetics Ferrofluid Science Experiment Kit. The ferrofluid itself is high quality with very fine particles, and it reacts beautifully to magnets. Everything in the kit—gloves, pipette, petri dishes—made the experiment clean and easy to set up. It works exactly as expected and feels like a well‑made, reliable product. Great for learning, teaching, or just having fun with magnetism.

マグシールド付きリールのオーバーホール用
こんなにたくさん要りません。少量で安く買えたらいいと思います。マグシールドを分解したらメーカーの保証は受けられませんので自己責任で。

Worth it
Used for school research and worked pretty well. Keep in mind that ferrofluid stains a lot and should be kept away from skin in a safe place.

I love it
This is a great product! I use it in my sensory bottles, and people love it. It can be a bit messy, so you need to be careful when handling it, and it can be difficult to clean up. However, I believe it's worth it. I have purchased several bottles so far and plan to continue buying more.
