Beach sand in bags (Firgrove OL16)

I’ve about 10 bags of beach sand (needed it to be this to be dog safe as play sand has chemicals in) , not sure on quantity or weight but we bagged them to what was reasonably moveable without giving us a hernia. Minimum order was half a tonne but we only needed to fill a sand pit. Take just a bag or what you can use - happy if it can be used :)
