What about a novelty magnet for that special someone?  These magnets are plastic-backed with a small magnet attached and measure approximately 45mm, so a lovely generous sized magnet.

This particular image is for a novelty retirement in pink!

Please note that your magnet image/colours may differ slightly from the image shown on your screen as it is difficult to capture the exact likeness, but in no way detracts from the great quality!  If you are at all unsure, we can send you a sample prior to purchase.
