Traditionally constructed using alnico material bar magnets are covered with two different colours that clearly indicate the north and south poles of the magnet. This makes them perfect for teaching young learners basic magnetic theory and principlesSpecial feature:1. Easy to build structures and models.2. Strong magnets keep every structure solid, yet easy to pull apart.3. All pieces made of tarnish-resistant, nickel-plated steel.4. Each set contains dozens of magnetic bars and balls.Educational Effect:1. Just an ingenious system.2. Simple construction with magnetic bars and chromed metal balls indulge kids and adults alike with structural possibilities that go on to infinity.3. There are absolutely limitless, creative possibilities for bi-dimensional and tri-dimensional designs and realistic models.4. It has it all model, such as physics, geometry, chemistry, architecture, and engineering.5. Suitable for over 5 years old children.1.Choose the product grade you need.2.Magnetic direction3.Choose the coating you want. No Coating or Customized4.Choosethe product sizeyou need.5.Packaging&Shipping1)By Sea: As the magnets have strong attraction and we will use the spacer to apart the magnets each other in case people will be hurt when take it out. Then, they will be packed in a white box of pieces each, several boxes to a carton. (Detailed package quantity should be made upon the real products)2) By Air: If the goods will be shipped by air, all the magnetic should be degaussed and we will use Iron sheet to shield.6.Payment7.Frequently asked questions1) What is the normal size of your product?
