Scarva Kilns Fibre Rigidiser From  £17.14

This is a good product at a reasonable price. Scarva were the only suppliers I could find without shipping from USA. Duties to the ROI cost almost as much as the item itself, but that can't be helped.
The rest of Scarva's extensive range is also great. I will likely be a returning customer.
Thanks for a professional and quick service

Product is what it is and works as intended. Delivery was fast to Ireland of not a little bit expensive. I would still buy again though
