What Open Sea Design Co does
Open Sea Design Co is a Brooklyn-based creative studio founded in 2015 by Melissa Constandse that designs and sells fine stationery and paper goods — including greeting cards ($3-$16), art prints ($10-$40), stickers (from $4), notebooks, correspondence sets, and adjacent ritual products — executed in original collage illustrations across occult, Victorian, esoteric, naturalist, and dark romantic themes. The underlying production is digital offset printing onto premium paper stocks, with all artwork developed in-house to build a proprietary design library.
The business operates a dual-channel model: direct-to-consumer e-commerce via Shopify, paired with multi-currency checkout and shipping to 100+ countries, plus B2B distribution through the Faire marketplace and direct wholesale to independent retailers. Pricing on consumer SKUs spans $3 (small card) to roughly $40 (top-end print), with gift cards priced $20-$100, indicating a low-AOV, high-SKU-count unit model rather than a contract or subscription model. There is no disclosed subscription tier, no marketplace Amazon/Target presence, and no data on repeat-purchase cadence.
The studio's most strategically distinctive commercial motion is a sequence of co-branded product collaborations with major film studios, including HAMNET with Universal/Focus Features (November 2025) and THE BRIDE! with Warner Bros. (February 2026), tying paper-goods releases to studio release windows as a calendarized revenue and press engine. The company is founder-owned, has not raised outside capital, and discloses no revenue, headcount, or financial metrics.

Open Sea Design Co competitors and assessment
Company assessmentDirect peers
- Snow & Graham: Independent stationery and paper goods studio producing greeting cards, journals, and gift products with a curated illustration-led aesthetic. Operates in the same DTC-plus-wholesale model and similar price tier.
- Rifle Paper Co. Founder-led, design-driven stationery and paper goods brand selling greeting cards, art prints, notebooks, and gift items through DTC and wholesale. Highly comparable in business model, channel mix, and aesthetic-led premium positioning, though Rifle Paper occupies a more mainstream florals/naturalist lane.
- Sugar Paper: Premium stationery and lifestyle brand focused on greeting cards, custom prints, and paper goods sold through DTC and specialty retail. Comparable founder-led design positioning and price tier to Open Sea Design Co.
- Yellow Owl Workshop: Small-batch paper goods and gift studio producing greeting cards, prints, and desk accessories with original illustration. Similar indie scale, premium pricing, and themed collection approach.
- Red Cap Cards: Artist-focused greeting card and paper goods company collaborating with independent illustrators. Comparable in artist-driven product development and specialty retail/wholesale channel strategy.
- Fox and Fallow: Boutique greeting card and stationery brand offering curated illustration-driven paper goods via DTC and stockists. Similar in scale, founder-led ethos, and product mix.
- Cavallini & Co. Vintage-inspired paper goods maker offering greeting cards, wrapping paper, notebooks, and gift items heavily influenced by botanical, anatomical, and antique imagery. Direct overlap with Open Sea Design Co's naturalist and Victorian aesthetic and similar product range.
Broad incumbents
- Paper Source: National specialty retailer of stationery, greeting cards, gift wrap, and paper goods. Operates a much broader assortment and physical store footprint but competes directly for the boutique stationery consumer.
- Crane & Co. Established heritage stationery brand (now encompassing the former Papyrus retail chain) selling premium greeting cards, personalized stationery, and paper goods. Significantly larger and more mainstream than Open Sea Design Co, but competes for the same premium card-shopping occasion.
Others
- Etsy (independent maker marketplace): While a marketplace rather than a peer brand, Etsy is the dominant channel and competitive context for indie dark-aesthetic stationery sellers. Many shoppers searching for occult/Victorian greeting cards default to Etsy sellers, making it an indirect competitor for the same niche buyer.
