Anyone has a good ideas to keep the umbilical cord stump?

I did a necklace with my son's umbilical cord and my breast milk, got it customized but now it's a product - https://www.keepsakebyryo.com/products/breastmilk-and-cord-hearts-duo-glass-locket

We kept ours in an angbao. http://www.keepsakebyryo.com/products/umbilical-cord-with-iridiscent-shimmer-charm-round. It's $139

I heard from the elders that u shud keep the umbilical cords of all ur kids together so they will be close when they grow up.

I did a personalized necklace with the stump n her baby hair

I actually keep it in an angbow with mine and my husband's!

you can put it into a stamp. huaxiataimaobi does it!

I kept it in an embroidered pouch in the safe

I just keep it in a angpao in a drawer
