This is a Kenko Lens Extension Tube Set with 36mm 20mm 12mm rings that fit CFE mount type Canon or perhaps Hasselblad cameras including the T70. Check your camera instructions or online to find out what mounting your camera has. This also comes with the Instruction sheet with conversion information. These will come to you connected as shown in first picture. To separate, simply twist the ring and remove. I call it vintage because the box does not have a UPC, which dates it to the late 70s or older. This is probably well used, but I have no way to check them for operation. They look to be in like new condition. It includes the original box and instruction sheet in various languages. No lens cap or cover for base (mounting to body) but you can use the ones from your lens when changing things out. View pictures closely for condition information, they are part of this description.
