It's not easy to find real nice vocaloid phone accessories that have good quality. So when I stumbled upon these while I was shopping around I was tempted to buy them [I did.. Getting Rin, Len and Luka]! I love the feel of the rubber straps... The printed material doesn't stick or leave. Len-kun on my phone is still smudge-free after I started hanging him on my iPhone for a few weeks. The price might seem a bit high for some but I guarantee that as long as you are looking for good quality and cuteness, every cent counts (: .
