The seams of the flap at the back of binder are not centered. The flap thus farm through! Closing the magnets do not fall in the face! (Delicate when it comes to + make a gift !!!). I returned to the seller. SAV response doudouplanet: refund of the product but not of my expenses back! For them it is not a defective product because the Lilliputians manufacturer has made them like that !!! Otherwise, a large notebook 21x29,7 does not fit in, then find out from the teacher before the size of the liaison notebook.
