The internal o-ring on the lower body keeps the pen from unscrewing while being carried in a pocket. Changes to the J-slot include moving it upwards as far as it can go to keep the pen under 5.5 inches in length; and the J-slot itself has been rounded more dramatically to draw the bolt into place when actuating the refill. Machined from durable 6061-T aluminum that is then heavily tumbled to provide a pre-worn but uniform finish that will only look better as it ages and gets more dings and nicks. Ships in our recyclable packaging with a custom vinyl sticker.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChoose between Pilot G2 rollerball OR Schmidt easyFLOW 9000 in black ink.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Karas Pen Co","offers":[{"title":"Pilot G2 Refill","offer_id":48629050376292,"sku":"KK5161-TMBLD-G2-BLCK","price":45.0,"currency_code":"USD","in_stock":true},{"title":"Schmidt EasyFlow 9000 - Black","offer_id":48629050409060,"sku":"KK5161-TMBLD-EFBLCK","price":45.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/3572\/9252\/files\/tmbldblt_sqr.jpg?v=1782321907","url":"https:\/\/karaskustoms.com\/products\/tumbled-aluminum-bolt","provider":"Karas Pen Co","version":"1.0","type":"link"}
