Always a pleasure to purchase from.
Ordered this and in less than a couple hours Tom had packaged, prepped it for shipping and even sent me a message showing my whole order! Excellent service and the product arrived quickly and was just as described! Will definitely be ordering again!
Excellent material, clearly labelled with the Verneuil colour number.
