The pens have odd looking caps which facilitate their connective ability, allowing each pen to attach to another with a simple click. The barrels are coloured in the same shade as their ink (generally true to colour apart from the neons) and are printed with the Faber-Castell name in gold debossing. They are not numbered or named, although there is a chart available online which names all 100 colours in the full set. The 20 pack of pens I am reviewing comes with 8 'Connector Clips' which can rotate pens when connected to create some cool makes (obviously more suited to children but fun for adults to play with too!)
These pens are water-based, so they don't bleed through paper- even on the thinnest stock. As with similar pens, seamless blending is a impossible to achieve but certainly passable as you can see on the bird I coloured. The nibs glide super-softly on the page and don't feel scratchy at all. The colours are really vibrant and 'pop' off the paper, giving great coverage and no pooling when held to the paper for a few seconds.
I love the fact that you can clip the lid securely to the top of the pen so it doesn't disappear, and the pens are unable to roll off the desk which is a big plus!
Faber-Castell Connector pens are amazing value for money to say that they are so well made with bright, vivid colours. You can buy them in different pack sizes from 10 (around £3.65) to 100 different colours (this largest set only seems readily available in Australia), so there are plenty of options depending on your budget.
These pens are a really great alternative to other water-based markers due to the sheer amount of colours they come in and how smoothly they colour. You can buy various sets on Cult Pens with FREE UK DELIVERY here, currently 20% off!
