Assists those with limited grip or the use of only one hand to open jars and bottles. The rubber grip holds the jar steady while opening and spooning out contents to prevent spillage. Three inverted rubber cones hold the container steady from 1inch (2.5cm) to 4 inch (10cm) in size. Such as drinks bottles or child proof medicine containers. A rubber base helps to stop the spill from not moving on smooth surfaces and can also be fixed permanently onto a worktop or contained in a drawer ready for use. Three opener cones are included to make opening tricky jars easier. The unique design makes it a smart addition to your kitchen.
