==Fountain Pens==
TWSBI has brought several affordable fountain pens to market over the past few years. The majority of their pens are [[piston filler]] pens, but they also have a couple [[vacuum filler]] pens. Prices range from $20 USD for the Go to $65 USD for the Vac-700R; there may be an additional $5 cost for the 1.1 stub nib in some models.

===Classic===
The [[TWSBI Classic|Classic]] is a solid-colored piston filler pen, with chrome trim. Available in five colors, it has an [[ink window]] on the section just above the cap threads.

===Diamond 580===
The [[TWSBI Diamond 580|Diamond 580]], often just called the 580, is a demonstrator piston filler pen. Available in two versions, the standard plastic version, and an aluminum version. Both versions are available in limited run colored options, with the cap, section and [[piston knob]] colored in the standard plastic version, and the section and piston mechanism colored in the aluminum versions.

''Prior versions include the Diamond 530, and Diamond 540''

===Diamond Mini===
The [[TWSBI Diamond Mini|Diamond Mini]] is a smaller version of the [[#Diamond 580|580]]. Still a piston filler, and available in the standard plastic or aluminum versions like its full-sized sibling. The cap screws to post.

===Eco/Eco-T===
The [[TWSBI Eco]], Eco for economical, is one of TWSBI's most affordable fountain pens. At only $30, it is an often recommended starter pen, as it is one of the cheapest piston filler pens on the market. 2018 also saw the introduction of the Eco-T model, T for the very slight "triangular" grip, as well as the piston knob shape being triangular instead of hexagonal. Available in a variety of colors, the Eco is a demonstrator pen with a colored cap and [[piston knob]].

===Go===
The [[TWSBI Go]] is one of TWSBI's more recent addition to their fountain pen lineup. It has unseated the [[Eco]] as their most affordable pen and retails for around $20. New for this pen is a spring-loaded [[piston]], allowing for easy, one-handed ink filling. 

===''Micarta - Discontinued''===
The [https://unsharpen.com/pen/twsbi-micarta-fountain-pen/ TWSBI Micarta] was TWSBI's only cartridge converter pen at the time. Made out of [[Micarta]], it had two versions, the original (v1), and the updated (v2). Both came with gold plated steel nibs, and gold plated clips, although v2 was also available in a clipless version.

=== Precision ===
The TWSBI Precision fountain pen features an all-metal construction. It has a brushed aluminium body with a hexagonal barrel.

===Swipe===
The newest offering from TWSBI. Available in Prussian Blue and Smoke. It uses Standard International cartridges/converters, however the cartridges and converters offered by TWSBI are a larger variation of the Standard International, and may not fit most pens. Included in the packaging is a TWSBI cartridge, a spring-loaded converter and a twist converter.

===Vac-700R===
The [[TWSBI Vac-700R|Vac-700R]] is a full sized vacuum filler pen. The Vac-700R is a demonstrator pen with a translucent smoke colored section and piston knob. The pen features an [[ink shut-off valve]], when the piston knob is screwed close, it shuts off the ink reservoir from the feed. In order to write for longer sessions, the piston knob needs to be unscrewed. This is very useful for frequent fliers as they won't have to worry about ink leaking while in the air.

''Prior versions include the Vac-700''

===Vac Mini===
The [[TWSBI Vac Mini|Vac Mini]] is the smaller version of the [[#Vac-700R|Vac-700]]. Available in full demonstrator, or similar to it's full sized sibling, with a smoked section and piston knob.
