The Link-It pens are joined by a special modular click system which pairs the two together with a sturdy, perfect fit. By simply pulling them apart, you separate the two and can link any two ends together- whether you want all your fineliners together and all your fibretips together, or all of your favourite colour duets joined in one pen, the possible 496 combinations are all up to you!
The Line-Up Fineliners come in a variety of 30 different colours, and the Link-It come in 16. The colours all have unique names, which I love as it's so much more interesting than 'light green, dark green'.
There are some really unusual shades included in the Schneider range, including Apricot, Coral, Alaska Blue and Nautic Green, which is a gorgeous marine tone.
The pens themselves perform really well, with smooth nibs that glide across the page and juicy flowing ink that appears very vivid on the page. I think the Link-It pens in particular are so handy as you can quickly switch from 0.4 to 1mm when you're colouring illustrations with varying line spaces.
The price is very reasonable at £0.95 - £1.30 per pen or in sets from £4.95 - £16.95, and the Link-It ends can be bought separately so you can purchase your favourite combos in either fineliner or fibre tip. Here's a page I coloured using the whole range of Line-Up and Link-It pens.
