Altoid Seibert

same as the Seibert, only the female performs the act with one or more Altoids in her mouth

The Seibert was awesome, but the cool tingle provided by the Altoid Seibert added a whole new dimension.

Seibert

Same as the Altoid Seibert, but without the Altoids.

The Altoid Seibert's cool tingle was a wonderful sensation. The Seibert was also nice but lacked the added coolness that makes the Altoid Seibert so special.
