Features:

Brand new and high quality.

Super strong Rare-Earth magnets - once they get stuck with each other，
    they are hard to break apart.

Can also be used to extend protected lithium batteries with recessed contact points.

Electrically conductive (making them suitable to extend recessed batteries).

Perfect for sticking notes on fridge doors

Ideal for DIY projects， whiteboard fixing， adsorption of various steel parts，
   fixing tissue box on the roof，etc

Ages7+ ages， both for kids and adults

Safety Warning:

1. When connecting two magnetic buttons，
    draw them close to each other slowly and gently.
    Hard crushing would cause damage
    and cracks in the magnetic material.

2. When you try to make the magnets apart，
    please slide and push the magnets one by one to
    avoid breaking them.
    Strong magnets， please take care.

3. Make sure keep the magnets are out of reach children and pets，
    it is not a TOY， and small magnets will pose a choking hazard.

4. Watch your fingers， as they are very strong magnets，
    which are difficult to pull apart and fly together quickly from far away，
    so it is very easy to pinch fingers between attracting poles.

5. Keep the magnets far way from medical devices，
    electronic products， and  magnetic media，
    as our magnets have strong magnetic fields which may  affect
    and or disrupt the functioning of these medical devices，  
    electronic products， and  magnetic media.

6. Magnets are fragile， they can crack， chip，
   or shatter if allowed to slam against each other.
   so make sure handle with care， eye protection glasses
   should be worn when handling magnets，
   due to launching of small  magnetic pieces at high speeds
   if shattering occurs.
