BAS1, Button tag and EID microchip (12mm).
This is an ideal tag for those who do not need nor want a very visual tag.
The microchip in the picture is of a discontinued range but if you wish to see the new type then please look at the Allflex standalone chip in this section.
You no longer need the Allflex chip implanter as the new chips come in a disposable pre-loaded applicator.
