Wondering how to go about popping the question?!
This Sterling Silver wine glass charm should do the trick...pop it on his/her glass and just wait for them to notice!
Have the wording personalised to say what you need to. The Sterling Silver tag measures 10mm x 40mm, and can carry up to 15 characters on each (of 2) lines. If that's not quite enough room I can downsize the text to fit 3 lines.
The hoop to wrap around your glass is Silver-plated, and has a diameter of 25mm, and a simple catch for opening and closing.
Great for a proposal, but also could carry a birthday message, a line from 'your song', or an in-joke aimed at your bestie :)
