First of all - is the font size. Depending on size the price of tubes is formed. The most common Nixie tube IN-14 has a middle size and thus is the most affordable and popular. The second criteria, which is also considered is a shape of the digit "5". The most available and common Nixie tube IN-14 has a upside-down "2". Due to some reasons (probably trying to save on production processes) soviet engineers decided to reuse some tools. For visual comparison see the image below.
The untrimmed version comes with factory made long wires and is good for side projects. The trimmed version is suitable for the NixieShop clocks that we make. If you need a replacement tube - this is the correct option.
Shipping is $10 for any number of tubes. Shipped via International Air mail with tracking number.
We can also combine your order with another to save on shipping. Tick the checkbox to exclude the second shipping fee and we will send tubes combined in a single package with the clock.
