Hey watercolor lovers! These Baohong postcards are seriously premium quality. Each pack comes with 20 postcards measuring 6x4 inches - perfect for quick paintings or taking on your travels. The best part? You get to try three different textures in one box: 16 cold press sheets (slightly textured, great for most techniques), 2 hot press (super smooth for fine details), and 2 rough (awesome for texture effects). They're made from 100% cotton fibers - not that wood pulp stuff - so they absorb water beautifully without warping or bleeding. At 140lb/300gsm, this is heavyweight, acid-free, archival-quality paper that won't yellow over time. Whether you're using watercolors, inks, markers, or even charcoal, these papers handle it all while keeping your colors vibrant. They're stiff enough that you don't need to stretch them, and they lay flat while you work. Perfect for beginners learning different techniques or pros wanting quality sketch paper. The cotton really makes a difference in how the paint flows and lifts. Such a fun way to create mini masterpieces!
