This magnetic pen holder will look great on your desk, transforming your pens into designer objects that literally stand upright on their tips.
You can even have fun with your pen by spinning it like a top, or even hang it from the support if you stick it under a shelf for example.
The tip can be placed in the central circle of the base, or you can tilt the pen slightly by putting the tip in one of the holes in the rosette all around, thus preventing the tip from drying out.

To make the support you need magnets 5mm in diameter by 5mm in length. You can get these magnets on Amazon for example with this link:

Insert 2 magnets per hole in the top of the support, be careful the magnets must be inserted in the same direction for each branch.

So you will need 8 magnets for the backing and an extra magnet to put in the body of the pen.

You can transform different pens into magnetic pens, for this you must open the pen, and cut the lead to a length of 50mm from the end of the tip (the length is very important). Therefore I advise you to carry out the transformation on a pen at the end of its life for which you can cut the lead where there is no more ink, however you can also cut a new lead taking care to wipe ink.
After cutting the lead to 50mm, you need to remove 5mm from the remaining part so that the total length of the two parts of the lead + the 5mm magnet still corresponds to the initial length of the lead (see photos).

The pens you can use must have a body with an inner diameter of at least 6mm.

Personally I obtained the best result using jetStream pens, because they have a body in the upper part perfectly adapted to the diameter of the magnet (see photos). Here is an Amazon link on these pens for example:

Pay attention to the direction of insertion of the magnet into the pen, if the pen does not sit straight in the holder it is probably because the magnet in the body of the pen needs to be turned around.
