{"type":"firestarter.listing","listing":{"id":"lst_gUr1wNTg","product_name":"Engineered Plastics \"Smoltem\" Pocket Fountain Pen - Ultem/Peek/Black Ultem","category":null,"description":"Natural Ultem, Black Ultem and Peek \nAfter launching the Engineered Plastics series in the full sized model I realized that it would be really nice to make our signature \"pocket pen\" out of these materials. Instead of redesigning the fantastic eyedropper friendly grip sections from the first Engineered Plastics pens, I decided to build on that foundation.\nThis enabled me to create this pen as a Pocketable Eyedropper that also takes short international cartridges like our best known pen, the Pocket Six. \nSimilarly I heard that people would like bigger pens from us. Noted! This small pen when posted is actually the second biggest Schon DSGN pen to date! The overall length is 138.5mm (full specs below) and the diameter of the body is a much lager 14.2mm. Funny how this pocket pen can be so big... but I love that about our pocket pens. Long live the screw post!\nNibs\nThis pen comes with a steel Jowo #6 nib.\nYou can add a Monoc Nib to this pen. You will need to add a Monoc to your order from here and select \"I'm Adding a Monoc\" as your choice of nib. \nO-Rings\nLet's get down to details - much like its Full Sized predecessor, this pen has an o-ring in the cap for a smooth closing action and leak proof seal. It is jam packed with o-rings in the section to create a strong pen for eyedropper use, filling the pen body with ink rather than using a cartridge. Here's a video about how to eyedropper a pen, why/why not, etc. Be sure to have some silicon grease handy as it makes the process much smoother and keeps the seals happy!   The o-rings will keep the pen sealed, so excessive tightening of the section to body and cap to body is discouraged as it may damage or deform parts. \n\nGrips\n\nI made a #8 (Bock 380) grip section for this pen in Black and Natural Ultem and that can be purchased here if you want to provide your own Bock 380 nib for the penI also made a Inkball Section which can be purchased with the pen or solo here.Mix and Match #6 sections in black and amber can be purcha","images":["https://cdn.shopify.com/s/files/1/0281/7862/products/IMG_4931.jpg?v=1664573850","https://cdn.shopify.com/s/files/1/0281/7862/products/IMG_3924.jpg?v=1664573850","https://cdn.shopify.com/s/files/1/0281/7862/products/BlackSmol.jpg?v=1664573850","https://cdn.shopify.com/s/files/1/0281/7862/products/Peek_33f0fb6c-edd7-4df0-9cac-48e31caa9b26.jpg?v=1664573850","https://cdn.shopify.com/s/files/1/0281/7862/products/IMG_3863.jpg?v=1664573850","https://cdn.shopify.com/s/files/1/0281/7862/products/IMG_3856.jpg?v=1664573850","https://cdn.shopify.com/s/files/1/0281/7862/products/IMG_3854.jpg?v=1664573850","https://cdn.shopify.com/s/files/1/0281/7862/products/IMG_3959.jpg?v=1664573850","https://cdn.shopify.com/s/files/1/0281/7862/products/IMG_3955.jpg?v=1664573850","https://cdn.shopify.com/s/files/1/0281/7862/products/IMG_3937.jpg?v=1664573850","https://cdn.shopify.com/s/files/1/0281/7862/products/IMG_3877.jpg?v=1664573850","https://cdn.shopify.com/s/files/1/0281/7862/products/IMG_3870.jpg?v=1664573850","https://cdn.shopify.com/s/files/1/0281/7862/products/IMG_3956.jpg?v=1664573850","https://cdn.shopify.com/s/files/1/0281/7862/products/IMG_3968.jpg?v=1664573850","https://cdn.shopify.com/s/files/1/0281/7862/products/IMG_3962.jpg?v=1664573850","https://cdn.shopify.com/s/files/1/0281/7862/files/black-smoltem-fountain.png?v=1750259779"],"price":240,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:17.225Z"},"share_url":"https://firestarter.network/l/lst_gUr1wNTg","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
