Tech Tips is a kind of a thimble that comes in different sizes and allows you to use tablets and smartphones, even if you are a bit clumsy.
The product can be worn over thick gloves, which means you do not have to remove when you want to use your phone.
Thimble was unveiled at the Consumer Electronics Show in Las Vegas, and costs about $10.
It's invented by Sri Velanki and she says that the idea came after her long nails bother her wehn using the smartphone.
Velanki, normally from India, who now lives in America, says: "I got the first iPhone in 2011 and it was difficult to use with long nails. So I decided to make a thimble that will be small, inexpensive and accurate. "
She added that "nails need to look good, and that no woman should sacrificed them for a device."
