Our most popular line, these approximately 2" to 2-1/2" high, magnetic, wooden name train letters fit on our train track and the wood track of Brio® and Thomas the Tank®, along with many other companies. These make a great unique personalized gift for a newborn baby, toddler, boy or girl. They even make great adult gifts for train fans! Please remember that these are for ages 3 and up so if purchasing for younger ages, they must be used for decoration only, until the child is older.
