Abstract: In this talk, I will argue that there must exist spherical brane shells in 4d that are overcharged, if the usual phenomenological compactifications of type IIB string theory with warped throats and anti-branes make sense. These shells correspond to classical over-extremal objects but without the usual naked singularities. The objects are made from D3-particles that puff into spherical 5-branes that stabilise at finite radii in 4d and whose inside corresponds to the supersymmetric AdS vacuum. We find that these objects can be significantly larger than the string scale depending on the details of the warped compactification.
