Spell Tracker for D&D

This is a spell tracker for D&D, I have included two versions, one with 2mm dia x 1mm thick magnets to lock better the cover (link for the magnets https://www.amazon.co.uk/Magnet-Expert%C2%AE-2mm-thick-Neodymium/dp/B007JTKHR6/ref=sr_1_6?dchild=1&keywords=neodymium+magnet+2mm&qid=1590233459&sr=8-6) and one without them but with a tighter joint. Further there is a token for each caster class.
