Hi Javed and apologies for the slow reply but I’ve been on holiday. I don’t actually supply these items or have any vested interest in them. I didn’t put the prices in this post intentionally as the manufacturers are likely to change the prices. This post was written some years ago, which is why I put a link to the suppliers website at the bottom of the post where people will always be able to access the most up to date prices. I’ve just checked the link and it still works, but here it is again: https://www.artsupplies.co.uk/item-perfect-paper-stretcher.htm
I hope that this helps.
