LET'S be honest- just how the Imperial Leather soap label somehow manages to stay secure weeks after use is something we've often pondered.
Even as the soap slowly wears away after multiple uses, that metallic gold label brandishing the brand's famous logo simply doesn't budge.
But it now appears that strong sticker has an important design function for the classic bar of soap - and even helps it last LONGER.
Taking to Reddit to search for answers, one intrigued user wrote: "You have no ideas how many times I've sat in the bath and stared at this sticker in amazement that it sticks to the soap 'till the very end."
Turns out we're not the only ones who are both perplexed and in awe of this marvellous metallic sticker.
Writing in reply, one user argued that "the sticker is meant to substitute for a soap stand and should always be placed downwards."
Another added: "The sticker forms something of a watertight seal against the soap, meaning the soap doesn't become slippery underneath."
A third chimed in with: "Older bathrooms used to sometimes have a chrome thing mysteriously fixed to the wall over the bath.
"It was magnetic and I think the metal label on the soap stuck to it, thus removing the need for a gooey soap dish... seemed like a good idea at the time."
In other words, that handy gold sticky prevents the soap from becoming mushy.
A spokesperson for Imperial Leather told the Mail Online: "Besides the brand identity, the sticker on the top is for a long lasting bar and preventing mushiness.
"When the soap is used, the sticker will make and keep the top surface, where the sticker is on, concave.
"After use, the soap is supposed to be upside down. The concave surface will help water run out from the bar and minimise the touching surface on a soap tray."
