As of May 9, 2016, National Band & Tag has acquired the Hasco Tag Company. One of Hasco’s product lines that we have kept on is the Flex-Lok Ear Tag line for livestock animals. These ear tags are different from other plastic ear tags because all male pieces have an open brass tip and it is the actual applicator pin that pierces the ear. We use a hot stamping machine to create large, black, permanently imprinted numbers and letters on the Flex-Lok ear tags. Multiple colors such as: Black, Blue, Green, Neon Green, Neon Orange, Orange, Pink, Purple, Red, White, and Yellow, are available, but color availability is subject to change based on current stock. Please call for availability of a specific color in a certain style. For those who prefer plastic ear tags for their livestock over our metal ear tags, Flex-Lok is a great alternative.
