A Japanese company is selling what might be one of the most uncomfortable and impracticable pieces of jewelry ever dreamed up.

BoDivas, based in Tokyo, is offering the strange item, which they call the 'Beachtail' and describe as 'sexy charms for bikini crotch'.

The metallic charms are meant to be worn through the crotch of bikini bottoms, so the decorations dangle between a woman's legs.

That's new... A company called BoDivas is selling crotch charms to wear with bathing suits

Odd: The design features a chunky chain that goes inside bikini bottoms, with crystals that hang on chains between the legs

Exotic... They are made in Japan and sell for around $20 each

The company oddly calls the jewelry 'classy' and 'very original', adding that besides in bikini bottoms, they can also be worn with panties, thongs, tangas, and shorts.

Each piece features a metal chain loop that is made up of half large, chunky links — which are meant to be worn inside underwear or bikini bottoms — and half more delicate links, which drape underneath the crotch on the outside.

There are also two loose chains that dangle between the legs, with some designs featuring gems on the ends.

The chains hang down 3 inches (7.5 centimeters) and are made of rhodium silver-plated brass.

Well that makes more sense... The company sells sex jewelry and notes that these can also be worn with underwear

Imagine seeing that on the beach! The uncomfortable-looking jewelry looks incredibly impracticable

The jewelry ranges in price from $19.50 to $22.50, and the company promises that the item is listed as a 'fashion strap' on customs forms.

BoDivas also sells other sexual body jewelry, including nipple rings, nipple 'nooses', and cvlitoris clips, which are clearly all meant for private wear.

And while the crotch charms might make sense in the bedroom, the company clearly suggests that this jewelry can be worn in public, too.

Unsurprisingly, though the crotch charms are available to buy on both Amazon and Etsy, no buyer has yet to leave a review.
