The items here make the best wedding time capsules. They're all stainless steel, polished to look their best, and ready to engrave. The 6x24" is the largest and a perfect for newlyweds. The 5x22" is popular, too. Both those sizes will fit wedding ceremony DVD's and other memorabilia from the wedding day. The 3x12 size is for the romantic time capsule and you can put a few letters and jewelry in it.
