What size is the bracelet you have on the photo? I think if you going to put extra 2 glass better with the next size up. As they do take up room and makes it feel tighter. I'm wearing 17cm I can have a max of 12 charms in which 3 of them is muranos any more it is uncomfortable. 18cm I can have 5 muranoes but have to have the bracelet full otherwise it falls too low on my hand and is too loose. My wrist is 14cm
i will probably choose a 18cm for the free bracelet promo, thanks for the info
