- 4mm is the best size since its not too big or too small. If you really want to "bling" ur accessories like; cellphone, mp3 player, cameras, or DS. etc. its the best becuz its not too big, and it will fit most accessories.
- i regret buyin my at 6mm becuz its too big, and its doesnt show much sparkly than the smaller kinds.
- E600 glue is the best. It holds on tight, and when you want to take your crystals out, it doesnt leave a nasty dry sticky glue behind like others. Also, it doesnt ruin the surface of your accessories. Thats what my friend told me, and she recommend it. Cuz she decorate her ds and got bored and took off the crystals out, and it look brand new like no one ever decorate it before.
see how big is the 6mm swarovski crystal are? Not as nice and sparkly than the smaller ones..
