Repair set of back cover sponge and mirror cushion for Canon A-1.
Please note this item is "custom kit", NOT Canon brand-name parts.
When the original light seals become old, it occurs light leaks and backdoor rattling.
It is time to replace the new Light seals, you do not have to worry about those problems any more.
Those are already cut, Ready to Use, You do not need to cut by yourself.
They are cut in a shape to fit the groove, so simply paste them in place.
The back side is processed with tape.
To apply the tape, apply water to the tape portion on the back side to temporarily reduce the adhesive strength, and then paste it in place.
Once the water dries, the adhesive strength will return.
