<p class="MsoNormal" style="text-align:left;">
<span style="font-family:Arial;font-size:10.5000pt;">Countersunk
magnets,refer to neodymium magnets with counterbored holes. Countersunk
magnets are used on boards and shelves asmagnetic holders,also could be
used as magnetic locks for doors.</span><span style="font-family:Arial;font-size:10.5000pt;"></span><span style="font-family:Arial;font-size:10.5000pt;">Fixing
curtain or door with a neodymium magnet is a good solution,but one of
the big difficulty is firmly fix the magnet onto the woods.<br />
