Official Indonesia Rugby balls by Gilbert. This range of rugby balls has been fully endorsed by Persatuan Rugby Union Indonesia and will be used by players, coaches and clubs across the entire country. The Midi will serve as the Official Souvenir Ball of Indonesia Rugby. Drawn in-house at Kuckreja, the new Persatuan Rugby Union Indonesia series was developed locally in-house at Kuckreja. The design took over a year to complete, and offers charming yet striking elements of Batik design.
