We are only able to send out a replacement lightpad if the one in your Scribe Kit arrives damaged or faulty.
You can find a similar lightpad in most retailers/online. It is an A4 lightboard/lightpad.
Don't forget that this can be claimed as a business expense in your tax return, for more info and support on this topic, please refer to the guidance on income and expenses from your local Tax office e.g HMRC in the UK and IRS in the United States
