Following the Government’s instruction regarding the national coronavirus emergency, Starrett UK closed on the 24th March until further notice. We look forward to continuing trade when possible to do so. All orders placed on and after this date will unfortunately not be shipped. If you would like to continue with your order we will have it delivered as soon as restrictions are lifted and it is safe to do so. If you have any questions at all please fill in an enquiry form on our contact us page - but in the meantime, stay safe everyone.
