30g of borax. I will repackage it into a bag with a zipper and ship it. Since 4g of borax is needed for 100ml of laundry starch, this amount is perfect for using up 750ml of laundry starch (*^^*) The box says 100ml of laundry starch, 100ml of water, and 50ml of borax solution, but about half that amount is easier for children to make ★ As shown in the third image, it's easier for children to make if you write the measurements with a marker beforehand (*^^*) Shipping is not available on weekends and holidays. Recycled materials will be used for packaging. - Product Name: Borax - Purpose: Slime making - Contents: 30g
