I ordered a sample and although I could see people getting 4 different coloured foam I myself only got one colour the blue. I am reviewing is the blue as I don’t know what the difference is with the colours. The item was much thicker then I expected and a nice size for a sample. I got a sticker the scalpel knife and blades, however I did not receive the £5 voucher in my box like others did maybe they are not doing this now. I was very impressed and as a person who does craft I can see myself ordering some and cutting out sections for my mica/bead tubes. It’s nice to see a company who offer a nice size sample I loved the thickness even to help soundproof your room and use them as storage. I would definitely recommend getting a sample and seeing for yourself, I was impressed and would recommend them to others.
