One of the really nice souvenirs I bought for myself (and some of my loved ones) are the handmade pieces made from little shiny colorful plastic beads. (I suppose they are plastic because of their weight). They sell seed beads in a lot of colors, usually monochromatic.
The jewellery was really affordable (about 2 Dollars for a keychain and 3-4 Dollars for a bracelet). Great to bring one for each of your friends and family. I brought a little yellow duck key ring for my little brother and a white and golden angel key ring for my mum.
They also had beautiful bags, belts and vests made out of the seed beads.
