Trinity Shiroma turns hand-painted postcards of landmarks into an $18,300 mail club
The Architecture Club mails 2,700+ subscribers a hand-painted landmark postcard each month at $8.88 — May 2026 profit near $18,300.
The Architecture Club (Trinity Shiroma)
What it had to solve
Trinity Shiroma, a 25-year-old artist in Orlando, Florida, held a master's degree in architecture but had no obvious channel for her hand-painted building illustrations. Subscription boxes and digital newsletters were everywhere; physical mail was not — yet searches for snail-mail gifts were rising and young audiences were actively cutting screen time.
How it works
In a world of newsletters, feeds and AI-generated images, some Gen Z customers are paying for the exact opposite: physical mail. Trinity Shiroma, a 25-year-old Orlando artist with a master's in architecture from California Baptist University, built The Architecture Club around that reversal — a monthly subscription that sends members a hand-painted 4x6 postcard of a landmark building.
For $8.88 a month, subscribers receive the postcard, a curated letter about the building's architectural history and a small craft or activity. Each envelope costs roughly $2 to produce, so even a single subscriber yields more than $6 of profit, and Shiroma spends about three weeks per cycle painting, writing and packing, with her parents helping seal the mail.
The format found an audience: the club went from its first mailing in September to 1,300 subscribers by December and past 2,700 within months, helped by her 43,000 Instagram and 27,000 TikTok followers. For the May 2026 issue she reported nearly $18,300 in profit — evidence that a one-person craft business can scale by adding subscribers, not production machinery.
Why it lands
- The subscription turns one hand-painted postcard into recurring revenue, so every new subscriber raises the value of the same monthly creative cycle.
- A landmark-building theme gives the paintings a collectible, educational hook that justifies $8.88 for a card plus a letter.
- The ~$2 cost per envelope leaves a margin over $6, making the arithmetic work even before the club is popular.
- Shiroma's own Instagram and TikTok audience did the discovery work, so the product could sell without paid advertising.
What it did
The club grew from its first batch in September to 1,300 subscribers by December, and past 2,700 paying members within months. For the May 2026 issue, Shiroma reported nearly $18,300 in profit — a single month's income from hand-painted mail, no platform cut and no digital product.
What you can take
A tiny, tactile product can beat a digital one when the audience is craving the opposite of screens: priced as a subscription, one hand-made object a month turns a craft skill into predictable income.
Since then
By mid-2026 The Architecture Club had more than 2,700 paying members and a best month of nearly $18,300 in profit, placing Shiroma at the head of a broader 'snail mail club' wave — peers such as Lucky Duck Mail Club (about 900 envelopes a month) and The Tiny Post (5,000 subscribers at $11) showed the format spreading. The trade-off is real labour: club founders describe the work as mostly packing and sealing rather than art, and Shiroma's parents help each cycle. She also sells the original paintings through her website, making each monthly landmark a small product line of its own.
