Fansells
Over the last few years I've ordered more than 20 diamond paintings and 2 paint-by-numbers kits from Fansells, and I've always been very happy with the quality. The only issue I've ever had was with my most recent paint-by-numbers kit, which arrived with the wrong paint colours. As it was a birthday present, I didn't have time to wait for a replacement. I contacted Fansells, explained the situation, and they refunded me straight away with no hassle. Excellent customer service and a company I wouldn't hesitate to buy from again. Highly recommended!
