Thanks for delivery
Excellent stuff using for model ship dioramas.
I personally use this for hobby and crafting purposes. It’s great, durable and easy to work with. The staff and delivery was amazing. Would use again in the future.
Let customers speak for us
from 49 reviewsDid 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

Very easy to use and cut . Great product.
