This is a modified insert board that allows you to use i-Type film with your Polaroid 600 series camera. Have you ever felt that 600 film is too expensive? Do you want to use i-Type film, which has more stable quality, but have given up because it's not compatible? This insert board is rechargeable and has voltage protection. It can be charged via a Type-C port and is fully charged in about 20 minutes.

Please let us know your model, and we will tell you if it can be installed. ⚠️Impulse/One600 series cannot be used because the internal space of the camera body is narrow. Also, all SX-70 series models (including 680/690) are not usable. ⚠️Battery life: Shooting is possible for two packs of film (as a guide). Type-C charging supported, fully charged in about 20 minutes. It takes time to manufacture, so it will take about 10-15 days to ship.
