You have the option to choose from black, blue or gold-colored ferrofluid. Available in 50ml or 100ml. Klock 100ml has a generous 2.5ml of ferrofluid. The glass bottle has crystal clear optics and is secured with a child-resistant cap. We only use EDU grade ferrofluid in combination with our world-renowned suspension liquid to produce the most superior quality of ferrofluid displays in the world. Magnets are included with every ferrofluid display sold on our site. For your convenience, the top of the display is magnetic, so it easily stores the included magnets when not in use.
