Rammstein have launched a new showcase highlighting some of the more unusual items they’ve received from fans over the years.

The band have already shared glimpses of fan-made crocheted dolls, Matryoshka dolls, Lego sets and more, with one of the more eyebrow-raising items revealed so far being a “penis flute,” which the group listed as unplayed.

Those items and others are set to be featured in a month-long exhibition at the band’s RammsteinStore in Berlin, Germany starting April 10th.
