I don't know why i didn't think of cuff links a long time ago! it wasn't until some one in chat mentioned that they had gotten a pair for some one they know that i thought, 'well duh!'
I think that regardless of age, if you ever loved legos, you always will. a good gift idea for the young and young at heart, bitsandbadges offers a lot of fun links, ranging from the traditional square legos to some rather nice round ones.
And what better way to present them than in a nice handmade box. goodstuff513 offers a few more boxes in different finishes along with other hand crafted wooden stuffs.
Whether the fun, lego cuff links or the sleek, traditional ones are more your recipient's style, a hand crafted gift box lasts a life time, and will be useful no matter how tastes change.
