Shirtbox

What Shirtbox does

Shirtbox is a direct-to-consumer apparel and accessories e-commerce brand operated by Teemill Tech Ltd, a private limited company registered in England and based in Freshwater on the Isle of Wight. Founded in 2008 and operating with a headcount of 11–50 employees, the company sells custom and pre-designed t-shirts, hoodies, sweatshirts and an expanding range of accessories including mugs, jigsaws, notebooks, water bottles and baseball caps. The storefront runs on the shared Teemill e-commerce platform, which also underpins the operational infrastructure for product design, ordering, fulfilment and the "Made to be Remade" take-back recycling programme.

The business model combines two revenue streams: (1) licensed branded apparel sold through fan and enthusiast verticals, including officially licensed collections with NASA, Peaky Blinders and Haynes Manual, and (2) a custom design studio that lets buyers create one-off or small-batch apparel without minimum order quantities. Pricing on core apparel runs £19.95–£22 per unit, with accessories and custom work positioned at varying price points. The site carries approximately 4,500 verified customer reviews at a 4.8-star average, signalling a distributed base of individual consumer buyers rather than enterprise or wholesale volume.

Manufacturing, materials and packaging position the brand around sustainability: products are made in the UK using organic cotton, with renewable-energy manufacturing and plastic-free packaging. The "Made to be Remade" programme closes the loop by recovering worn products for recycling. Distribution is primarily UK-focused, with international shipping available. Customers are individual consumers and small-volume custom buyers (small businesses, events, gifts), with no enterprise or B2B anchor accounts disclosed in the available data.

Revenue model

1. Direct E-commerce Product Sales: Shirtbox sells printed t-shirts, hoodies, sweatshirts, mugs, and other personalised merchandise directly to consumers through its shirtbox.com storefront. Revenue is generated per unit sold at fixed price points. The primary model is one-time purchase with no subscription element. Personalised/custom orders command a slightly higher price (£21.95–£22) than standard graphic tees (£19.95). The company also sells mugs (£10) and other accessories. Bulk order discounts are available for custom prints (e.g., for stag/hen nights).
2. Licensed Merchandise Sales: Shirtbox sells officially licensed merchandise for brands including NASA, Peaky Blinders, and Haynes Manual. Revenue from these licensed products flows through the same direct e-commerce model but includes royalty/licensing costs passed through in the product pricing (£22 for licensed tees vs £19.95 for standard designs).
