Arrived with no broken pieces, well packaged
20 sets, each wrapped individually.Core without bobbin measured at:(L x W x H) 25.7 x 20.3 x 6.3mmCore center is 6.2 x 6.2mm (Area 38mm^2)Electrical measurement for reference if you want to wound your own coil:9 turns of wire: 105uH, saturation at 1A9 turns of wire, air gapped at 0.15mm (About two paper thickness):17uH, saturation 9ANote, double of turns causes square of inductance. Thus, for example, 18 turns of wire will result in an inductor of 400uH and half of the saturation current (0.5A).
