The first versions of LastSwab were not TPE. They were silicone. They worked, in the sense that you could clean an ear with them and rinse them clean afterwards. But silicone has a texture — a slight drag — that does not feel right for repeated daily skin contact. You notice it in a way that you do not notice cotton.
That was the first material decision: silicone out, TPE in. TPE is softer, smoother, and closer to what cotton feels like against skin without being absorbent. It took a few rounds of prototypes to land on the right durometer — the measure of TPE hardness. Too firm and it felt medical. Too soft and it compressed too easily. The final material is somewhere in the middle.
The Shape Problem
The temptation when redesigning a familiar object is to redesign the shape too. A cotton swab is a very simple form. We looked at alternatives — different tip profiles, different stick geometries, different case designs. Most of them were solutions looking for a problem.
The insight that stuck: people already know how to use a cotton swab. If the reusable version requires learning a new technique or adapting a habit, most people will not adopt it. The goal was to make the product familiar enough that picking it up for the first time felt like picking up something you already knew.
We have written more about this in Why We Kept the Cotton Swab Shape. The short version: the shape we settled on is almost identical to a disposable cotton swab. That was not laziness. It was the point.

The Case
A reusable swab needs a home. Without a case, it gets contaminated in a bag or a drawer. The case protects the tip and keeps the swab clean between uses. It also makes the product portable in a way that a box of disposable swabs is not.
The snap-close case was designed to be compact enough for a pocket, durable enough to survive a year of daily bag use, and easy to open with one hand. Getting the snap mechanism to close securely but open without effort took more tooling iterations than we expected. It is a small part of the product that gets used hundreds of times.
Kickstarter and the Volume Problem
LastSwab launched on Kickstarter in 2019 and funded significantly over its goal. The campaign was validation that the concept worked and that people would buy a reusable cotton swab. It was also the point at which the manufacturing challenge became real.
Prototypes are made in small numbers, often by hand or in small production runs. Kickstarter creates a fixed, large order quantity from day one. The question is no longer "does the design work" but "can we make 10,000 of them to the same standard as the 50 prototypes."
The answer, for the most part, was yes — with some iteration. The case tolerances needed tightening. The tip attachment required better quality control at the moulding stage. A few early units had tips that were not fully bonded and separated. We caught that in the quality check process, but it informed the manufacturing spec going forward.
What We Would Do Differently
More time on manufacturing validation before the campaign. The design was ready; the production spec was not quite. Prototypes made by a skilled technician and units produced on an injection moulding line at volume behave differently. The gap between those two things is where most product development risk lives.
We also underestimated packaging complexity. Packaging seems like a downstream problem. In reality it affects production line efficiency, shipping cost, and the unboxing experience — all of which matter. We have revised the packaging since the initial launch.
Where It Landed
LastSwab has shipped millions of units since the Kickstarter. The core design has not changed significantly since the initial production version — the material, the tip shape, the case. That stability is a signal that the prototype work was thorough enough. Not every product gets to a version 1.0 that holds. This one did.
Frequently Asked Questions
When did LastSwab launch?
LastSwab launched on Kickstarter in 2019 and shipped to backers the same year.
How many units did the Kickstarter raise?
The LastSwab Kickstarter raised significantly more than its funding goal, with backing from tens of thousands of supporters across multiple countries.
Has the design changed since launch?
The core design — tip material, shape, and case — has remained largely consistent since the initial production version. Minor refinements have been made to the case tolerances and packaging. The product is functionally the same as the one that launched.
Is LastSwab still made at the same factory?
We work with trusted manufacturing partners. The production process has been refined over successive runs to improve consistency and quality control.
