Extras Needed:

1x Hotglue gun or a common super glue

6x magnets 10mmx2mm

1x nail file

100x of your best doublesleeved cards

How to Assemble:

1. Use the nail file to polish the binaries for the top part; DO NOT insert the top parte without have polished both the parts or it could seal both of the parts;
2. Use the glue to fix the magnets, I personally reccomand to put all the three magnets with the same orientation for both sides (---;+++)
3. Let the glue do his work for about 30mins (it dipends on what kind of glue did you used)
4. Put your cards on it and you should be good to go
