These sets of pens include 9 pens that are erasable with the two included erasers, and 9 'magic' pens that change colour when you apply either of the two included 'changer' pens.
The pens have a broad 2mm nib and narrow barrel which is lightweight and comfortable to hold. Both set have barrels that match their ink colour, but the Magic pens have different coloured caps that represent which colour they will turn after you've applied the changer pen.
The erasable pens are great fun to make patterns and designs over your colouring pages, to give them a personal customisation. They're also particularly useful for when you go out of the lines, as the eraser completely eradicates any ink that it touches.
The magic pens are again a fun edition to your colouring as they create double the colours, all by simply passing the changer pen over the areas you want to change colour. You can also try your hand at creating some pop-off-the-page 3d text!
Kids will absolutely love these pens as it's so exciting to watch your marks disappear or change colour! The pens are very safe with vented caps and water-based, washable ink.
Overall these are awesome for children but also a cool way of changing up your adult colouring pages to make them unique!
