The warmth of its curled-up body on your slippers is carved into the leather's texture; the wind stirred by its wagging tail is carved into undulating arcs; the softness of its licking across your fingertips is transformed into shallow grooves. Those mornings and evenings stained with fur, those eyes that light up at the sound of footsteps, are all meticulously captured in the inscriptions. This is no ordinary leather; it's a palpable heartbeat, a companionship that will never fade.
