Amazing product 👏
Great service, quick delivery and a good price
Easy to order trouble free service with smooth prompt delivery
Good prompt delivery was exactly as I was expecting
Excellent quality and arrived promptly and undamaged. I bought the 20mm to make a base for a diorama which is difficult to find in the UK. Amazon sell very small pieces only.
Great material and service, will definitely buy here again.
Perfect .. thank you.
The insulation board was perfect for the job, all delivered promptly and in good condition.
Fast shipping, good product quality. I highly recommend.
Quality delivery and product.
Did exactly what it says! The boards were easy to work with and were delivered on time and at a very good price. Unfortunately, I let myself down with my maths and didn't order enough for my room and I had to pop down to a local flooring company who charged me more for the small area I wanted to cover than what this company charged me for the entire room!
Good quality, great price, well packaged for delivery and arrived super quickly A++++++
Great
It go here well packed and in one piece
Very easy to use and cut . Great product.
