Our main goal is to produce high-quality and cruelty-free products. Creating Premium sketchbooks means making sure that we’re acquiring the best possible materials and that our clients know exactly what has been used to bring their sketchbooks to life.

Transparency is our domain. We’re not a corporation, so there’s no secrecy; we’re always happy to share the components of our sketchbooks; from paper through threads to glue and covers. There are very specific reasons behind our choices: all the elements come from manufacturers with a long history and experience in their field. The fact that our suppliers meet strict ecological requirements as well as ensure an ethical environment means a great deal to us.

We’re attaching all the components that we use and the description of the brands, below.



Fabriano Kovalsketchbooks

Artistico is a watercolour paper made with 100% cotton produced with mould made process, a special industrial process that reproduces the typical characteristics of hand-made paper, which is why it is also called “manomacchina”.

Here are the highlights of this paper: improved surface sizing, stronger surface, 4 deckled-edges, fixed-point watermark, Vegan Friendly product.

“Artistico” paper represents the culmination of eight centuries of Fabriano papermaking tradition.


The absence of acid guarantees the inalterability over time of the paper. Ideal for watercolour, tempera, gouache, acrylic, ink, charcoal, wax, graphite, felt-tipped pens, drawing and printmaking (etching, lithography and silk-screening), announcements and invitations. The watermark (only on sheets) reproduces the Fabriano logo and the inscription “50% COTTON”.

The new features implemented in Fabriano 5 Enhanced exalt the characteristics of “Fabriano 5” through salient aspects that distinguish this paper: 4 deckled-edges, new surface sizing formulation that facilitates colour lifting (colour removal), surface more resistant to repeated brush strokes, Vegan Friendly product.

Arches Kovalsketchbooks


In KOVAL Sketchbooks we use:

Made on a cylinder mould (traditional process): quality close to that of paper made by craft methods. The slow turning of the cylinder enables the fibres to be deposited evenly and spread in all directions over the wire. The fibres are distributed evenly, the paper slackens uniformly when wet, giving the artist more control. This process can produce papers with a high grammage and exceptional resistance to scratching and erasing, when they are gelatin sized to the core. Only papermaking on a cylinder mould can produce paper with deckle edges.

Its 100 % long cotton fibre composition gives the paper its beauty, a natural, lasting whiteness and an inimitable touch as well as strength.

Exclusive to ARCHES®, gelatin sizing to the core preserves the lustre and transparency of the colours whilst preventing paints from penetrating into the paper. It allows superposing of washes and gives it added strength to resist erasing and scratching without tearing or linting. It also allows paints to be removed, either wet or dry, easily revealing the whiteness of the paper. ARCHES® Aquarelle can absorb a large amount of water with limited deformation.





In KOVAL Sketchbooks we use:
