device tlKit can be worn with comfort and without 



danger h\ those who dehght in ocean sports, such as high diving, 



swimming, water polo, and 



the Hke, consists of two soft 



rubber disks mounted on a 



:.tein. These chng to the 



lUter ear cavity, keeping the 



■ar-drum protector in place, 



and permitting easy insertion 



and removal while, at the 



same time, preventing the pro- 



"OcE.\x' Eak Dbim Protector. tector from falling out. When 



in place the "Ocean" ear-drum 



protector is invisible. The protector comes in one size, virhich 



fits any ear, due to the elasticity of the rubber of which the 



disks are composed. The "Ocean" ear-drum protector is sold 



on display cards containing two dozen pairs neatly packed in 



small boxes attached to the card. (Safety Ear Drum Protector
