What makes this bumper incredible? - you might ask.
It is thin. Incredibly thin. We use less than 1 millimeter of polyamide to cover the iPhone's antenna system - the thickest part of this bumper measures 0.7 millimeters. This allows to plug in the 30 pin "dock"-connector without removing the bumper. Aditionally, there is a tiny rim around the glass sections of the iPhone to avoid contact of the glass with a surface the iPhone is put on.
The Strong & Flexible material from shapeways is so durable that this thin layer will keep your iPhone completely safe when dropped.
In contrast to other iPhone-cases, this bumper emphasizes the elegant design of the iPhone 4 instead of concealing or disturbing it.
The incredible bumper was designed following Apple's strict guidelines for iPhone cases - this assures a precise and tight fit and unconstrained functionality.
In everyday use, the incredible bumper almost feels like it isn't there - but when your iPhone needs to be protected, it is.
The Strong & Flexible material is dishwasher-safe. If your bumper gets a little dirty over time just put it in your dishwasher and it will look like new!

We recommend the white polished material, as it has a really nice surface.
iPhone 4 CDMA and iPhone 4S bumpers coming soon!
