This is an expander made by Evernew. It was used about 40 to 50 years ago to train the upper body. It has been stored in a warehouse for the past few decades without being used. The springs show discoloration due to aging, but I believe there are no problems with use. Evernew expanders are primarily spring-type, simple, and durable fitness equipment used for strength training of the upper body, such as the chest, shoulders, and arms. [Features and Main Uses] ● Training Effects: Strengthens the chest, back, shoulders, and upper arms. ● Structure: Compact design using metal springs, doesn't take up much space. *Please refrain from purchasing if you are looking for a new item or are overly concerned about condition.
