Hi,
For characteristics, I will recommend you our tutorial documentation page about it.
www.hikashop.com/support/documentation/i...html#characteristics
A characteristic of a product does not add something to the original price, but it allow you to override (change) the full price.
An option add an extra price to a product, it's an addition. For the characteristics, it's a replacement.
