The sticky tape we need, badly

The roll of tape nobody could crack. A surgeon just solved it, with a trick from the operating theatre

It starts with a moment most people will recognise: you’re wrapping a birthday present, reach for the tape, spin the roll once, twice, ten times – hunting for that maddening invisible edge that seems to vanish every single time. Rajan Bhojwani, a british surgeon, was in exactly that situation, watching an episode of The Worst Witch with his two daughters, when a character on screen wished for a spell to find the end of the Sellotape. Something clicked.

Then came a second moment, this one from his day job. An eye surgeon by profession, Dr Bhojwani said he hit on the idea after a partially sighted patient apologised for giving him a badly wrapped present – because she was unable to find the end of a roll of tape. Two frustrations, one insight. The result is SeeTheTape: the first redesign of sticky tape in decades, now even backed by € 40,000 from Dragons’ Den investor Steven Bartlett. The fix, it turns out, was hiding in plain sight.

The science behind the black core

SeeTheTape is wound around a dark-coloured cardboard inner rather than the conventional white one. The € 2,00 product – unfortunately, still not sold in continental Europe – makes the tape’s edge immediately visible – solving one of life’s great frustrations.

The physics behind it come straight from the operating theatre.Dr Bhojwani uses a process called scleral scatter to see fine details such as small scratches in patients’ eyes. He realised that mounting see-through tape on a dark roll uses the same principle: light passing through the curved transparent roll is absorbed by the dark background, making the fine edge more visible. In other words, the innovation didn’t require a new material, a new adhesive, or a new manufacturing process. It required someone who understood how light behaves through transparent surfaces, and who had the lateral thinking to apply that knowledge to a roll of tape sitting on the kitchen table. The results in early testing were striking: one man who couldn’t find the end of conventional tape after a full minute found it on SeeTheTape in 18 seconds. Another who took 30 seconds with ordinary tape got it in five. Simple numbers, but they tell the story of an idea that genuinely works.

From family conversation to a patented product

Dr Bhojwani described the invention as starting as a “throwaway family conversation.” What followed was anything but throwaway: four years of design work, patent applications, prototype testing, and partnership building, including collaboration with a charity supporting partially sighted people, whose members helped test early versions of the product. The Partially Sighted Society of Dorcaster, UK, became a retail partner from the outset, stocking SeeTheTape on its website: a reminder that what began as a universal annoyance has particular significance for the millions of people with visual impairments for whom conventional tape presents a genuine daily barrier.

The patent itself attracted notice beyond the business community. A patent examiner from the UK Intellectual Property Office, highlighted SeeTheTape as a standout example of how a simple idea can lead to a patented invention and a useful product – noting that it was Bhojwani’s experience as an eye surgeon that inspired the solution.

Why this is more than a novelty

It would be easy to file SeeTheTape under “amusing invention” and move on. The internet is full of solutions to minor domestic irritations, most of which dissolve as quickly as the problem they claim to fix. But this one deserves a second look, considering who the problem actually affects most. For the majority of sighted adults, the missing tape end is a mild annoyance, a few seconds of frustration before a birthday party or a packaging job, but for people with reduced vision it can make wrapping a present, sealing an envelope, or completing a simple DIY task genuinely difficult or impossible. The Partially Sighted Society’s immediate partnership with SeeTheTape signals that accessibility, not novelty, is the product’s deepest value proposition. The tape is currently priced at £1.49 – comparable to standard tape at most supermarkets – which removes the premium-product barrier that often limits accessibility-focused inventions to specialist markets.

The stationery and packaging tape market is dominated by a handful of major manufacturers – 3M, Scotch, Sellotape – who between them produce billions of rolls of tape each year. The inner core has been white for as long as tape has existed. No one changed it. It took someone whose professional life is built around seeing what others miss – literally, in the case of corneal scratches – to notice that the colour of a cardboard tube could eliminate a frustration experienced by everyone who has ever wrapped a present. It is a reminder that the most useful innovations are often not the most complex, but the ones that ask the simplest possible question – what if we changed this one thing? – and then take the answer seriously enough to do something about it.
