Is there an additional charge for personalization?

An initial printing plate fee and a minimum order quantity apply. The plate fee varies depending on the plate required.
Standard printing has no additional charge. Certain options cost extra, such as printing on both the top and inside of a case or in the centre of a microfibre cloth.

How long does production take?

Typical preparation and production times are:

  • In-stock, non-personalized items: 1 business day.
  • Personalized cases, cleaners and bags: approximately 2 weeks.
  • Care kits: approximately 3–4 weeks.

These are estimates and do not include shipping time.
