lens element removal tool kit. This kit includes suction bulb, short tube 33mm, long tube 95mm, 2 pieces 20mm suction cap, and 2 pieces 4.80mm suction cap. Not made for use with water. Made by UN of Japan.
As the name states it is a sucker(suction) tool. Made for removing lens elements from group or element housings. When used carefully, I was able to hold, remove and place large elements, 65mm diameter and smaller. It is a high-quality tool and lasts for years. I know because I purchased one of these tools from Vivitar in 1978 and I still use it today. Some of the pics in this ad are of the old box and tools.
The is tool is not made to remove elements by twisting the tool in the hope of turning the element in place.
