Photo Paper Dryer for Darkroom with USB-C Port, Upright Slot 4x5 and 5x7

Entry-level darkroom device: this photo paper dryer, made by 3D printing process and weighing 760g, is suitable for beginners looking for a simple and reliable way to dry wet paper quickly in the darkroom or outdoors. MULTI-SLOT FIT One slot holds 4x5" horizontal or 5x7" vertical paper and holds each sheet upright for versatile, damage-free drying in all popular formats. Stepless airflow control: A rotary knob adjusts a continuous air flow at room temperature, which draws moisture from the wet paper and thus avoids heat exposure to the gelatin emulsion layer. Upright suspension protection: vertical slot keeps the wet emulsion layer away from flat surfaces on both sides, reducing scratches and sticking when air drying while standing. Flexible power supply thanks to Type-C A universal Type-C connector allows the dryer to be operated via a power bank, so it works even in a corner of the darkroom or on a makeshift workbench outdoors without any power outlet restrictions.
