The Twsbi Go is an entry-level fountain pen. It has the same nib as the more popular Tswbi Eco, but uses a simpler filling mechanism.
The Twsbi Go has a simple, spring-loaded piston filling mechanism that is less precise than the twist piston on the Eco and 580, but still effective. One bonus of the push spring style is that it is very fast to fill and empty, many the Go a very fast pen to clean. Combined with the price, this makes it a great pen for testing fountain pen ink.
The Tswbi Go uses the same steel nibs as the Eco, but a smaller nib than the more expensive 580 series.
The Go does not have a clip, making the pen a non-starter for some people. One thing people like the Go is that is has a wider diameter than is typical, so it’s an uncommonly wide pen for the price. The downside of this is that it uses a lighter, cheaper feeling plastic that that found on the Eco, which is only a few dollars more.
