About this item

• [PURE COTTON PAPER] Experience the texture of 140lb (300gsm) pure cotton paper. Unlike wood-pulp alternatives, our acid-free sheets provide high-quality pigment absorption and resist yellowing over time. Suitable for watercolor, gouache, and acrylic painting
• [FLAT DESIGN – NO FOLDING ISSUES] Say goodbye to uneven creases and fold buckling. The 4 x 6 inch flat format provides a clean, professional painting surface that stays straight and sturdy. Suitable for framing, postcards, or DIY invitations
• [ABSORPTION & STURDINESS] Designed for wet media, the cold-pressed texture allows smooth and even pigment distribution. The long-lasting 300gsm paper resists pilling and excessive buckling even under heavy watercolor washes
• [COMPLETE 108-PIECE STATIONERY SET] 36 flat watercolor cards, 36 white envelopes, and 36 decorative sealing stickers. Suitable for handmade wedding invitations, Mother's Day cards, and graduation notes
• [HELPFUL ARTIST TIPS] Use low-tack tape to secure the edges and minimize warping during wet painting. Always paint on the textured cold-pressed side. Allow the artwork to fully dry before removing tape to protect the cotton surface
