Shure SM81-LC Cardioid Condenser Instrument Microphone for Guitar, Piano, and...The Shure SM81 is a high quality, unidirectional condensermicrophone designed for studio recording, broadcasting, and soundreinforcement. Its wide frequency response, low noise characteristics, and lowRF susceptibility have made it a standard for applications involving acousticinstruments, especially guitar, piano, and cymbals.

The Shure SM81 is a high-quality, unidirectional condensermicrophone designed for studio recording, broadcasting, and soundreinforcement. Its wide frequency response, low noise characteristics, and lowRF susceptibility have made it a standard for applications involving acousticinstruments, especially guitar, piano, and cymbals. POWER REQUIREMENTS NOTE:This microphone requires phantom power and performs best with a 48 Vdc supply(IEC-61938). However, it will operate with slightly decreased headroom andsensitivity with supplies as low as 11 Vdc. Most modern mixers provide phantompower. You must use a balanced microphone cable: XLR-to-XLR or XLR-to-TRS. Built to withstand the rigors of regular stage and studio use, theShure SM81 unidirectional condenser microphone is a great choice for studiorecording, broadcasting, and sound reinforcement. Its wide frequency response,low noise characteristics, and low RF susceptibility make it a perfect matchfor applications involving acoustic instruments, especially guitar, piano, andcymbals. Ruggedly constructed, the SM81 operates on phantom power and performsover a wide range of temperatures and humidity conditions. It comes with aswivel adapter, attenuator-switch lock, foam windscreen, and case for carryingand storage. Key Features Frequency response.

Perfect little sunscreen
Sun protection factor: 50 Sun Protection Factor (SPF), Size: 0.49 Ounce (Pack of 1)
Easy for my son to apply himself at summer camp. Compact size for his backpack. Only downfall is it goes on white until fully rubbed in, which is normally fine but when my son is trying to get his face himself at camp it is hard for him. Wish it went clear on its own.

Works very well
Sun protection factor: 50 Sun Protection Factor (SPF), Size: 0.49 Ounce (Pack of 1)
Sent this with my daughter to preschool application was very easy for the teachers. Overall the stick was a little bit smaller than expected but it goes a long ways. Was really happy with the overall ingredients in this product versus others. Well worth the money and my daughter was more open to having it because of the application being in a stick.

White cast
Sun protection factor: 50 Sun Protection Factor (SPF), Size: 0.49 Ounce (Pack of 1)
I like having sun screen sticks like this to have the kids carry around in backpacks at summer camps/sports practice so they can re apply - but this one goes on white and is more of a challenge for the kids to get all rubbed in. Wont purchase again

Easy to use and the perfect size for a childs face. Of course it's a plus that Moana is on it, but not necessary. Works good.
