The site doesn’t say what diameter it is.
There is a separate pack made up for 1.75mm and for 3mm. Choose which you prefer from the dropdown menu.
I must have been blind there for a bit
Wow great 
I’ll give it a try! You’ve got some tough competition in the UK premium PLA market though!
Yeah there is some tough competition out there. We believe our stuff is excellent quality and we know the product as we make it ourselves. We are hopeful that we can find a place in the market.
Around $70 shipping for a free sample pack? Too steep for me. It sounds like a good deal for people who aren’t international.
We are based in the UK and shipping outside Europe is really that expensive for us for normal order sizes. Unfortunately this means we probably aren’t that competitive for Customers in North America.
I do understand. Thanks for the info either way I’ll keep your site in mind and maybe something will happen down the road.
