Pair of Lego cufflinks
Although they're not named as such - probably due to potential copyright infringements - these are most certainly Lego cufflinks.
They're actually billed as Forever Young cufflinks, designed by Jacqueline Sanchez. Handmade, in your choice of colour, they have a sterling silver base with a sandblasted plastic centre in the colour of your choice.
As they're custom made, so allow three weeks before shipping. They retail for $150 (that's around £80).
