The biggest size we offer... each piece is a few cm longs which make it a little heavy to input many of them if you are making a necklace or a bracelet... but one or two unit could work well! They are great to use as a center piece pendant... and people found other uses to them too... for example: use them as figurine ornament, some use the one that has a good base as incense stick holders and what's for sure - they can be collected! So why not start collecting today?!
