The cotton swab was invented in the 1920s. The design has barely changed since. This is either a testament to how well the original worked, or a sign of how rarely anyone questioned the one part of it that didn't need to stay the same.
Probably both.
Leo Gerstenzang and the birth of Q-Tips
The story begins with Leo Gerstenzang, a Polish-American entrepreneur living in New York in the early 1920s. Watching his wife wrap cotton wool around a toothpick to apply it to their baby's skin, he saw a product opportunity: a pre-made, ready-to-use cotton-tipped applicator.
He founded the Leo Gerstenzang Infant Novelty Company and began producing them under the name Baby Gays. The name later changed to Q-Tips — the Q standing for quality. By the 1930s they were a household staple across America.
The basic design: a thin paper or plastic handle, cotton tip on one or both ends. Simple to make, simple to use, cheap to produce at scale.

Why the design never changed
The cotton swab is a good design. It fits naturally between two fingers, provides fine control, and is sized for the tasks people use it for — cleaning the outer ear, applying topical products, detail work. The form solved the problem it was designed for.
What nobody really questioned for decades was the material assumption: that cotton is the right thing for the tip, and that single-use is the right model for the object.
Both assumptions were shaped by the context of mass production in the 20th century. Cotton was cheap, abundant, and familiar. Single-use products were a signal of modernity and hygiene — clean and disposable, not shared and washed. The design reflected the values of its era.
That era lasted a long time. Q-Tips are still made the same way today. So are the vast majority of cotton swabs on shelves around the world.
A hundred years of cotton
Consider the scale: an estimated 25 billion cotton swabs are produced and discarded globally each year. Each one used for a matter of seconds. The cotton tip absorbs what it contacts, the plastic or paper stick holds it together, and then the whole thing — three seconds of function — goes in the bin.
The form works. The material was never updated.
This is a pattern across many everyday objects. The original design solved a real problem well enough to become standard, but the material choices it made were never revisited — not because they were right, but because the object was too familiar to question.
What an update actually looks like
Updating the cotton swab doesn't mean replacing it with something unrecognisable. The shape still works. The form still fits the hand and the task. What changed — in LastSwab's case — was the tip material and the model.
Cotton out. TPE in. Single-use out. Reusable in.
The result is an object that performs the same tasks, fits the same habits, and fits in the same space in a washbag or bathroom shelf — but doesn't need to be thrown away after one use.
It took a hundred years to update. It didn't need to take that long.
LastSwab — the cotton swab shape, updated for a different century. One swab replaces around 1,000 single-use disposables.

Frequently Asked Questions
Who invented the cotton swab?
Leo Gerstenzang, a Polish-American entrepreneur, invented the mass-produced cotton swab in the early 1920s after observing his wife improvising a cotton-tipped applicator at home. He marketed them as Baby Gays, later renamed Q-Tips.
Why hasn't the cotton swab design changed?
The form of the cotton swab — thin handle, cotton tip on each end — solved its core design problem effectively and became deeply familiar. Because the shape worked, there was little pressure to update it. What wasn't questioned was the material model: that cotton is the right tip material and that single-use is the right approach.
How many cotton swabs are used each year?
Estimates vary, but figures in the range of 25 billion globally per year are commonly cited. Each swab is typically used for a few seconds before being discarded. The scale of single-use here is substantial — which is part of what makes a durable reusable alternative worth considering.
What is LastSwab made from?
LastSwab has a TPE (thermoplastic elastomer) tip — soft, flexible, and non-porous, meaning it rinses clean rather than absorbing and holding residue like cotton. The case is made from plant-based bioplastic. The goal was to update the material and the model while keeping the form factor that already worked.
