(9 x 11. 7 cm) Finish Glossy Exposures per Unit 10 exposures per pack Development Time 45 seconds at 70°F Caution This film uses a small amount of caustic paste. If any paste appears, avoid contact with skin, eyes and mouth and keep away from children and animals. If you get some paste on your skin, wipe it off immediately, then wash with water to avoid an alkali burn. If eye contact occurs, quickly wash the area with plenty of water and see a doctor. Keep discarded materials away from children, animals, clothing and furniture. Limited Warranty See information on the film box.
