Sedulus 主課本 特大 A4 紅色 附薄紙

The tissue paper pages are a nice touch for protecting my wet paintings, and the 20% larger format gives me room to spread out diagrams without cramping. The 110 g/m² paper handled fountain pen ink without bleeding, which was my main worry.

I needed a larger format for my botany drawings and the oversized A4 with the 20% extra space makes a real difference. The tissue paper between pages keeps my wet paintings from bleeding onto the next spread.

The 110 gsm paper takes wet watercolor washes without bleeding through, and the tissue interleaving keeps each page pristine. I’ve already filled half the book with botanical sketches and notes.
