Gift Wrapping

For those that don't have the time, can't do it or simply want the luxury touch, we offer a professional gift wrapping service here at The Online Pen Company.

Our gift wrapping consists of beautiful two-sided wrapping paper with a burgundy exterior and a golden interior. Each item is then wrapped individually, and then tied with a golden bow. The wrapping is then finished with a personalised handwritten message card, which is attached to the corner of your item.

The process to have your item gift wrapped is nice and simple

  • 1. Choose your pen
  • 2. Use the drop down menu on the product page to add gift wrapping to your item, and then use the next menu that appears to add a personalised message.
  • 3. Add the product to the basket, and continue shopping.
