People, people....
These soap scraps have been repeatedly handled by someone probably who has been to the bog, and handled so much that they have worn down in size.

For the love of god put them in the bin!
Soak the bits to soften them, then squeeze them all together. Let them dry before using them. Or, you could spend some money on an overpriced item like this...
