LastSwab features premium materials and a clever design. Like your typical cotton swab, it is two-sided. Surprisingly, the swab doesn’t feature cotton at all, instead it uses a soft-feel tip made of TPE (Thermoplastic elastomers). We chose TPE (instead of silicone), because the melting temperature between the rod and the TPE is closer and for that reason the bonding is much better. The bonding is crucial, because without good bonding the tips will end up detaching from the rod ending up in places you don’t want it. The swab is easy to clean; a dash of soap and water does the trick, however it is also dishwasher safe, but you can only wash it at 50°C (122°F) or below temperatures. The use of acetone, like nail polish remover should also be avoided to clean it, as it may damage the TPE.
