To further prolong the life of the Nib, we recommend flushing the nib unit after every few uses, if not after every use. When used in a fountain pen, flush the entire assembly with pen cleaning solution (couple of drops of household ammonia + couple of drops of dish soap + water), in between pen uses and if not using the pen for long periods of time . If using as a Dip nib in a penholder, we recommend that you wipe down and clean the Zebra G nib after use. Typically, the nib starts to rust if it comes in contact with any liquid (water, ink, etc), so wipe and keep it dry when not using.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e\u003cimg height=\"81\" width=\"477\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1476\/8374\/files\/708F337B-6BEC-4899-BC36-1AF0F53774BE_480x480.jpeg?v=1574328909\"\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp style=\"padding-left: 90px;\"\u003e\u003cb\u003e\u003cimg height=\"218\" width=\"278\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1476\/8374\/files\/Dip_Penholder_Ebonite_Green-Brown_ripple_Zebra_g_480x480.JPG?v=1576539902\"\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eThis 10 pack of Zebra G nib singles can be used with  Osprey Pens Zebra G Fountain pens or in other dip Penholders.\u003c\/b\u003e\u003c\/p\u003e\n\u003cul style=\"display: inline !important;\"\u003e\n\u003cli\u003e\u003cbr\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cdiv id=\"enap-gallery-49990\"\u003e\u003c\/div\u003e\n\u003cdiv id=\"enap-gallery-popup-49990\"\u003e\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv id=\"enap-gallery-49924\"\u003e\u003c\/div\u003e\n\u003cdiv id=\"enap-gallery-popup-49924\"\u003e\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Osprey Pens","offers":[{"title":"3 Zebra G Titanium Nibs","offer_id":40306134712389,"sku":"Nib-ZG-Res-3","price":15.0,"currency_code":"USD","in_stock":true},{"title":"5 Zebra G Titanium Nibs","offer_id":40306134745157,"sku":"Nib-ZG-Res-5","price":20.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1476\/8374\/products\/image_77436659-2114-4762-9742-9b1cb68e2821.jpg?v=1574153970"},{"product_id":"jowo-compatible-6-steel-eef-ef-f-m-b-bb","title":"JoWo Compatible #6 STEEL EEF, EF, F, Med, B, BB nib","description":"\u003cdiv id=\"enap-gallery-50894\"\u003e\n\u003cp\u003eThis listing is for Size 6, polished stainless-steel\u003cstrong\u003e  \u003c\/strong\u003eOsprey nib unit compatible with Pens that \u003cstrong\u003eaccept JoWo nib assemblies.\u003c\/strong\u003e Available in Extra-Extra-Fine (EEF), Extra-Fine (EF), Fine(F), Med (M), Broad(B), and Double Broad (BB) tip sizes.\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eThese nibs are great for everyday writing.
