# Cryptic Notebook Kits Baron Fig's 'Lock & Key' Has a Hidden Puzzle Inside By Joey Haar | Published 2018-01-18 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/cryptic-notebook References: [producthunt](https://www.producthunt.com/posts/lock-key-by-baron-fig) & [baronfig](https://www.baronfig.com/products/lockandkey) Not only is designer notebook company Baron Fig's new 'Lock & Key' set an attractive way to take old-fashioned, [handwritten notes](https://www.trendhunter.com/trends/qui-magnetic-pencil-system), but the cryptic notebook hides a puzzle in its pages. The notebook itself serves as the lock and the pen the key, and only through a combination of the two can consumers unravel the mysteries inside. The Lock & Key set plays off its mysterious theme in its design. The notebook features a [maze illustration on the cover](https://www.trendhunter.com/trends/locked-crack-the-code), and it comes with a fold-out insert that seems to lay out the puzzle of the set. The pen, a [smooth brass implement](https://www.trendhunter.com/trends/zero-mk2), includes a holder engraved with a codex that unveils the meaning of the runes placed throughout the notebooks pages. Lock & Key is a special edition set, though the pieces are only aesthetically different from Baron Fig's Confidant Notebook and Squire Rollerball pen. ## Trend Insights (Trend Hunter) - Score: 5.6/10 - Popularity: 86% | Activity: 74% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Art & Design](https://www.trendhunter.com/artdesign) > [Design](https://www.trendhunter.com/design) ## Key Themes ### Key Themes Behind This Trend - **Interactive Notebooks:** Opportunity to create notebooks with hidden puzzles or interactive elements for a unique note-taking experience. - **Mystery-themed Stationery:** Potential for designing stationery products with cryptic designs and hidden codes to cater to mystery enthusiasts. - **Combining Analog and Digital:** Innovative chance to merge traditional pen and paper note-taking with digital elements to enhance the interactive experience. ### Where This Applies - **Stationery:** Stationery industry can explore creating mystery-themed products that offer additional engagement through puzzles and hidden codes. - **Gifts and Novelty:** Opportunity for gifts and novelty industry to tap into the demand for unique and interactive stationery items with a cryptic touch. - **Technology and Creative Tools:** Potential for technology and creative tools industry to develop digital platforms or apps that complement the interactive aspects of cryptic notebooks. ## Related on Trend Hunter - [Tetrahedral Desk Puzzles](https://www.trendhunter.com/trends/desk-puzzles.md) - [Leather-Bound Connected Notebooks](https://www.trendhunter.com/trends/connected-notebooks.md) - [Modular Refillable Notebook Systems](https://www.trendhunter.com/trends/notebook-system.md) - [Adventure Subscription Packages](https://www.trendhunter.com/trends/curious-correspondence.md) - [Transparent Fountain Pens](https://www.trendhunter.com/trends/maze.md) - [Hybrid Luxe Card Holders](https://www.trendhunter.com/trends/noteanote.md) - [Elegant Desktop Brainteaser Toys](https://www.trendhunter.com/trends/craighill-tetra.md) - [Elegant Analog Note Systems](https://www.trendhunter.com/trends/note-taking-kit.md) - [Interactive Fantasy Fiction Books](https://www.trendhunter.com/trends/curious-readers.md)
