Sculpted sandstone walls glow in shades of deep crimson, burnt orange, and gold, their sinuous curves layered like frozen waves of stone. Light pours through narrow openings above, illuminating the flowing forms with an ethereal radiance that reveals the geological artistry carved by water over millennia. Sewn from a durable canvas-like exterior with a soft lining and made to order, in three sizes up to one that fits a tablet. A catchall for toiletries, art supplies, or small electronics, carrying an independent artist's work instead of a plain zip bag.
