As some of our customers operate in the medical supply chain our factory and online shop are both still open!

These are indeed unprecedented times. At TRM we have taken the necessary steps to comply with the Government's "Anti Virus Measures". Colleagues, where able, are working from home. Our factory is still operating using additional protection and we are also operating an increased level of cleaning.

Our delivery partners APC, Fedex, UPS and DHL are still operating and aim to have your orders delivered to your door as quickly and as safely as possible.
