That gives a very large ink capacity, so refills are rare.\u003c\/p\u003e\u003ch3\u003eHow long is the pen?\u003c\/h3\u003e\u003cp\u003eIt measures 119 mm when capped, which is why it works so well as a pocket or planner pen. Posting the cap brings it to a comfortable writing length.\u003c\/p\u003e\u003ch3\u003eCan I use ink cartridges instead?\u003c\/h3\u003e\u003cp\u003eNo. This is a dedicated eyedropper pen, so it is designed for bottled fountain pen ink filled directly into the barrel.\u003c\/p\u003e\u003ch3\u003eWhat does the shut-off valve do?\u003c\/h3\u003e\u003cp\u003eTurning the knob at the end of the pen closes the ink channel. That keeps ink from flooding the nib while the pen is stored or carried, and you simply open it again before writing.\u003c\/p\u003e\u003ch3\u003eWhat nib sizes are available?\u003c\/h3\u003e\u003cp\u003eThis pen uses a stainless steel nib. Please select the nib size shown in the options above before adding it to your cart.\u003c\/p\u003e\u003ch3\u003eWhich inks should I avoid?\u003c\/h3\u003e\u003cp\u003eStick to standard bottled fountain pen inks. Shimmer, pigment, and iron gall inks are not recommended in an eyedropper pen because they can clog or stain the acrylic.\u003c\/p\u003e\u003ch3\u003eIs it a good first fountain pen?\u003c\/h3\u003e\u003cp\u003eYes, if you enjoy using bottled ink. The steel nib is smooth and easy going, and the huge capacity means you can write for a long time between fills.\u003c\/p\u003e","brand":"OPUS 88","offers":[{"title":"Black White \/ F","offer_id":67680225329252,"sku":"OP95102907C-1","price":128.0,"currency_code":"AUD","in_stock":false},{"title":"Black White \/ M","offer_id":67680225362020,"sku":"OP95102907C-2","price":128.0,"currency_code":"AUD","in_stock":true},{"title":"Black White \/ B","offer_id":67680225394788,"sku":"OP95102907C-3","price":128.0,"currency_code":"AUD","in_stock":true},{"title":"Black White \/ 1.4mm","offer_id":67680225427556,"sku":"OP95102907C-4","price":128.0,"currency_code":"AUD","in_stock":false},{"title":"Blue Strap \/ F","offer_id":67680225460324,"sku":"OP95102907C-5","price":128.0,"currency_code":"AUD","in_stock":true},{"title":"Blue Strap \/ M","offer_id":67680225493092,"sku":"OP95102907C-6","price":128.0,"currency_code":"AUD","in_stock":false},{"title":"Blue Strap \/ B","offer_id":67680225525860,"sku":"OP95102907C-7","price":128.0,"currency_code":"AUD","in_stock":true},{"title":"Blue Strap \/ 1.4mm","offer_id":67680225558628,"sku":"OP95102907C-8","price":128.0,"currency_code":"AUD","in_stock":true},{"title":"Red Dot \/ F","offer_id":67680225591396,"sku":"OP95102907C-9","price":128.0,"currency_code":"AUD","in_stock":true},{"title":"Red Dot \/ M","offer_id":67680225624164,"sku":"OP95102907C-10","price":128.0,"currency_code":"AUD","in_stock":false},{"title":"Red Dot \/ B","offer_id":67680225656932,"sku":"OP95102907C-11","price":128.0,"currency_code":"AUD","in_stock":true},{"title":"Red Dot \/ 1.4mm","offer_id":67680225689700,"sku":"OP95102907C-12","price":128.0,"currency_code":"AUD","in_stock":true},{"title":"Green Dot \/ F","offer_id":67680225722468,"sku":"OP95102907C-13","price":128.0,"currency_code":"AUD","in_stock":true},{"title":"Green Dot \/ M","offer_id":67680225755236,"sku":"OP95102907C-14","price":128.0,"currency_code":"AUD","in_stock":true},{"title":"Green Dot \/ B","offer_id":67680225788004,"sku":"OP95102907C-15","price":128.0,"currency_code":"AUD","in_stock":false},{"title":"Green Dot \/ 1.4mm","offer_id":67680225820772,"sku":"OP95102907C-16","price":128.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/9871\/8052\/files\/OPUS-88-Mini-Pocket-Fountain-Pen.jpg?v=1791603424","url":"https:\/\/www.touchfive.com.au\/products\/opus-88-mini-pocket-eyedropper-fountain-pen-demonstrator","provider":"TOUCHFIVE","version":"1.0","type":"link"}
