With our increased global presence Grena products were targeted by some low-cost followers who intended to place very similar products on the market.

Having received several reports on of this activity, we decided to protect our products and help customers clearly distinguish between the genuine Grena products and the fake ones. Please keep in mind only the genuine Grena products offer patients' and users' safety.

Always pay attention to the labeling of the products received. In particular make sure the details of the manufacturer (the name and the address) are shown according to those listed on the proper certificates. The reference numbers must be the same like presented in the appropriate declarations of conformity and official marketing materials. Keep in mind that the official colour of Grena's staplers is deep green.
We are taking some extra precautions to make sure the genuine products are easily identified.

Since May 15th, 2010 all Grena products are marked with a laser printed hologram.
