Gently used 4x5 development tank that holds up to 4 sheets at a time and only needs 475 mL (16oz) of developer. Original box and instruction included; in excellent condition. Made of ABS plastic (not 3D printed), easy to use and takes up little space to store. Currently $96 new, selling for $70 plus actual shipping costs (weighs about 1lbs); payment via PayPal. Let me know if you have any questions.
