simply attach a few Ring magnets with any rope-like material that is at hand

these little Green pin magnets retain and display important documents that need to interrupt our lives long enough to attract attention and be acted upon

Durable Construction: Neodymium core encased in a steel shell for enhanced durability and focused magnetic force

Magnetic Liquid Ferrofluid EFH1 - 50mL L_52mm and the closed-loop is 22mmUses for our Magnetic Liquid Ferrofluid: Ferrofluid is a ferrous nano particle liquid that reacts in the vicinity of a magnetic field. Many of us will first remember seeing this magnetic liquid as part of a science experiment at school. Ferrofluid is used as an excellent demonstration tool for magnetic experiments. The particles respond to the magnetic field to create a wondrous display of amazing shapes and once the magnetic field is removed the
