Unfortunately, there are no letters puzzle with single-color uniform, unpatterned (ideally vowels andersfärbig) letters. From the flashy colored this one is the best. Although the letters are actually too small for the age group for which they are intended, but does not bother especially. We have the puzzle for over a year (someone plays a few times a week so) in use and it is still in very good condition. Although I had only thought that the glued pattern would come off soon, they hold excellent so far. The letters are rel. precisely milled. Many symmetric letters really fit in only one direction in the recess, but our children and days children had soon heraussen.
