These wire mobiles will be made to order for customers who buy 3+ fish from our glass fish collections. The mobiles will be specifically balanced to the amount, type and weight of each individual glass fish. We can discuss approximate sizes with you. Please contact us if you need something special. Please be aware that if you choose standing mobiles, the stone included will significantly affect shipping prices! We cannot reflect this in our shipping options so we will be happy to discuss this with you beforehand if you contact us with a query.
