I purchased the 100mm thick by 400mm wide rolls to line the inside of a van as a camper conversion. The wool mix was of a good quality and consistent thickness that plumped out to 100mm after a bit of shaking. I recommend finding a strong cutting mechanism because dress making scissors will struggle and will take three or more shallow cut passes to cut a roll. The odour is not strong as people would make out and after a week I can't smell any sheep like smells coming from the van. Very happy with the product and found the price for delivery very reasonable too.
