I ordered several wooden boards to paint icons. Upon delivery, half of them showed scratches on the surface to be painted or saw marks on the side. The wooden boards are made without the care necessary for the production of works of art. Dal Molin has not had any hearing for my request for replacement of the unusable art supply nor for a refund saying that "these details have no importance". I do not recommend this business.

A company that is worth a visit for the wonderful and wide range of basic materials from shaped wooden boards, chalked, tools and colors: everything you need to create icons or pyrographic works. They have wonderful painted icons, books and also organize courses on the subject. Courteous, competent staff, generous with information and suggestions. Worth a visit.

The solid lime wood boards, purchased by me online from the well-stocked Dal Molin Carpentry, to carry out carving work, have an excellent quality/price ratio and are available in a vast number of formats... The packaging of the products sent was also very careful and received with very punctual delivery. Compliments!
