An optional 20\u00d720\u202fcm insert allows you to cast half-sized blocks for brick bond wall arrangement. Removable cast-in handles make it easy to handle the finished concrete blocks. These small concrete blocks enable structures to be assembled considerably faster, thereby reducing working time. The top studs and bottom recesses ensure stable stacking and are compatible with other block sizes. The mould is compact and lightweight, making it easy to transport and handle on site."}
