LettrLabs’ Handwritten Insert Media offers a flexible, envelope-free format for packaging inserts, product mailers, and direct placement into boxes, kits, or bags. Available in both flat and bi-fold formats, these cards retain our authentic, handwritten feel — just without the mailing components.
Overview
Insert Media is a great option when you're already sending a physical package — and want to include a handwritten message that feels genuine. Whether you're running an ecommerce loyalty campaign or building trust post-purchase, this format adds a thoughtful, tactile layer to the unboxing experience.
You can choose between:
- Flat Handwritten Insert (single panel)
- Bi-Fold Handwritten Insert (double panel, side fold)
Both versions are printed and written on thick 100# card stock and can include full-color branding on the front panel.

- Loyalty Program Touchpoints – Include reward info with a personal message.
- Subscription Box Extras – Add a rotating handwritten message each month.
