Many people enjoy having an Esu along with them where ever they may travel to. The smaller Esu/Oko and the Locket Esu/Oko were created so that one could have the possibility of this energy being right at their side and offerings could be made to this tool wherever you are at. Many parents give one to their children to take along while on their daily journeys. Some people also have the need to be more private about their Orisa practice (unfortunately) so this enables them to have what they want without others becoming so aware of it. Also lack of space can be an issue. College students find this size tool more adaptable to their situations. The energy itself is there whether it be with a smaller tool or a larger tool they are created equally! LETTER OF AUTHENTICITY, A PRAYER, A LIST OF OFFERINGS APPROPRIATE FOR OKO AND INSTRUCTIONS ON HOW TO WORK BEST WITH THIS GREAT TOOL WILL BE INCLUDED IN YOUR SHIPMENT.
