In 2017 we sponsored the SO 2017 event in Czeladź (Poland) again. Our tunnels and tunnel holders were successfully used during the competition. In addition, we awarded the winners of the categories finals Small, Medium and Large – Andrea Tagliapietra (IT), Olga Kwiecień (PL) and Tereza Králová (CZ) who got the gift vouchers to receive free any 6 meter Agiflex tunnel.
