The days of disposable plastic products are numbered – alternatives are needed. LastObject’s reusable cotton swabs show that the market is ready for change. The company’s basic and beauty cotton swabs are both made of high-quality materials. The tip is made of THERMOLAST M, a compound from KRAIBURG TPE that is often used for applications in the health sector.


Every day, 1.5 billion cotton swabs are produced worldwide that each to be used only once, and that’s where LastObject’s mission begins.


As the first step, this project is supplying reusable, hygienic and reliable alternatives to single-use items people use on a daily basis, where more than 500,000 LastSwabs have been sold to customers all over the world. LastObject is thus responding successfully to EU Directive 2019/904, which bans single-use plastic products and will be coming into effect from mid-2021.

The basic requirements for the reusable cotton swab, LastSwab, are durability and quick and easy cleaning. Close attention was given to these qualities during the development process. Another requirement was for the product to be skin safe and not cause any irritation when in repeated contact with the skin.


In Denmark, KRAIBURG TPE is collaborating closely with Teknisk Agentur, a trusted local distribution partner. The choice of material for the flexible, soft tip was a compound from the THERMOLAST M series. This compound was also superior to its competitors in relation to processing options, adhesion and look and has the following properties:

  • Hardness: approx. 40 Shore A

  • Tensile strength: 8.0 MPA

  • Elongation at break: 800%

  • Tear resistance: 11.5 N/mm


The compound provides adhesion to polypropylene and polyethylene, high abrasion resistance, weldability and freedom from animal ingredients. It is processed using injection molding and extrusion. The rigid stick is made of polypropylene.


The case is made of recycled ocean waste plastic (OWP) from the Danish company Zeaplast who collects plastic from the ocean and rivers in southeast Asia and recycles it. The entire product is molded by AMP, a well-known Danish injection molder.


The product effectively and measurably helps to save raw materials and waste, while reducing the carbon footprint. “The entire process was very straightforward – all the way from identifying the product through to the service. KRAIBURG TPE, Teknisk Agentur, their Danish materials distributor, and the injection molder AMP are reliable partners who are helping us make the future more sustainable,” said Nicolas Aagaard, Co-founder at LastObject.
