This is not a sex toy. This is the TAD, a mobile phone accessory for the long-nailed or keypad-confounded. It's pretty simple really: You insert the pointy bit and then slip the ring over your thumb--hey presto, you've got a pointy thumb.
It might look a bit gimmicky, but if you've got very long nails you'll know how difficult it can be to tap buttons--the TAD could be the answer. It comes with three swappable pointers for different size keys--the pointed one you can see in the picture is for touch screens. It's not perfect, but after a little adjusting it does work OK, although it'll take some getting used to.
According to its creator, the TAD also doubles up as a ring protector, which is useful if you're going to play sports or just want to make sure it doesn't get scuffed on a night out--or you could just wear it as a ring itself. It comes in black, white, red, pink, blue, and green. If you're keen on trying it out, it'll only set you back a few bucks from the TAD's online shop.
