The external designs of each EGG reflect the internal details within them – with a variety of EGGs to choose from, you’re sure to find a perfect match. The thick inner surface is adorned with an array of densely-packed fine protrusions. The highly elastic elastomer firmly tightens, enveloping you with bumpy stimulation. The EGG is a single-use, disposable product. Simply use as directed, then dispose of in the same casing. Sample Lubricant Included.
