These links are very colourful and have many textures. Most of the letters were instantly identifiable, with just maybe 3 that needed working out. The majority fit together easily and the rest will be ok for older or more experienced children to manage. My young Grandson enjoys playing with them in short sections, for the moment, not caring at all what letters he has. He's having great fun pulling the easier ones apart. I can see many uses for these in the future, picking out the different colours aswell as learning the letters. Also helping with co-ordination and fine motor skills. They come in a handy carry-bag, which make them easy to take with you when visiting friends and family, if not being used on the way. I wanted a pack with more links so found this suited me.
