Adding shortening to a Pi makes it fatter - but this kind of shortening makes your Pi a little slimmer! This black short-style microSD adapter slides in where the SD card goes but is 9mm shorter. This makes it stick out a lot less and makes for a more elegant (and less accident-prone) Pi. All you have to do is pop in a microSD card for a sleeker machine! The outer edge of the SD adapter has a deep grove for a fingernail to pull on for removal. | Because its just a shorter microSD adapter, this short microSD adapter will work in any Raspberry Pi case (our, other, low-profile microSD adapter card is a bit thicker and doesn't work in all cases, including the Adafruit Pi case and PiBows). Protrudes from edge of Raspberry Pi 8mm when installed | This microSD adapter also worked great in our Macbook pro - load it up with a 64 microSD card and you've got a ton more storage, but without the sticking-out of a normal sized SD. | IMPORTANT: This product will only appear flush with the following MacBook models: MacBook Air 13" (late 2010 - 2017), MacBook Pro 15" (mid 2012 - early 2013) | Check The Dimensions: 24mm x 23mm x 2.1mm / 0.95" x 0.9" x 0.08".
