Tree in 3d received by carrier. Form a little small but the furniture assembler sy easily find (up in 40 minutes only) and more wool keys are provided. Very good quality and yet my two Griffon did not spare !! Only downside, the perches are not very large so the cats above a little when they put sy ... The ball 2 mouse hold well and maisonettes are quite large for a comfortable rest of my 2 large (5.2 kg, 4kg still growing) I do not regret having bought it !!
