No more embarrassing jokes about your operatic ring tone. The Cellphone Call Signal Pen has a little light that flashes when a call comes into your muted cellphone:
The pen has a signal range of about 6 ft and comes with 2 LR-41 batteries. The batteries and pen ink cartridge can be easily replaced. Works with any standard cellphone.
Alas, doesn't seem to be in stock right now.
