When my kids were smaller, we had a couple of those magnet building sets, and over the years the pieces have slowly but steadily disappeared. Now every so often I’ll find a piece stuck to a lamp or something, which is actually a lot more amusing than finding stray Lego with your bare feet. Ahem.
Still, this 100 piece MagnaCase Magnext set made me a little nostalgic for the good old days, when my kids thought magnet were the coolest! things! ever!! At $17.99 (free shipping eligible) it could provide countless hours of entertainment.
Until you start to the lose the pieces, anyway. (But it comes with a case, so maybe you can avoid that particular fate….)
