Attaching a new Ultra Shave blade cartridge to your Ultra Shave razor handle is easy as long as the cartridge is the right way up.
Make sure the four small holes with blue filling (on the back of the blade) are pointing upwards.
Line up the middle of razor handle (A) with the middle of the back of the blade (B), then push the razor handle into the blade.
When you push, the two connector arms from the razor handle should slide into the tracks on the blade.
You will hear a “CLICK”, this confirms that the blade is connected onto the razor.
