All the markers and the eraser in this set work well- vibrant colors that erase cleanly after a short period of time.  The real star of this set, though, is the caddy!  It makes my heart happy because it’s made of 90% recycled material.  It’s ultra light and can be hung by magnet or adhesive strips (both are included), so will work in almost any situation.  I was concerned about this being hung on a slightly angled surface because the markers might fall out- but the front of each marker compartment has a lip to hold the marker securely in place for storage!  Fantastic.
