Size :8.7*8*3cm . Weight :50g. I highly recommend this small wallet. It can play, and can also hold some small sweets and earphones. It is very suitable for adults and children.made out of silicone safe and non toxic. Water resistant and helps with anxiety, stress, adhd, and restores the mood. Great for exercising children’s logic thinking ability, which is very interesting and inspiring. Perfect gift for all ages and great for on the go!
