So for the little cubes have a nice bonding force. I've already bought the second set because the take away no place and adhere to the Wall a bed of leaves. The journal information of the seller are no exaggeration. Half a centimeter Pabier is not a problem, keeps super, more then no longer holds. Sticky you only few leaves on, you can not get the magnet to draw almost straight away, so best to push away laterally. For just pull the small cubes is always a bit too small to grab. But genieal and I can recommend the parts without a murmur.
