These Bend n' Build sticks are clear wax over brightly coloured string that hold their shape and stick together with no glue needed. The great thing about Bendables, is that they work really well (not all waxed sting sticks do). Because clear wax is used to cover string, they don't leave a residue, and they're sticky enough that your creations stay together, but still undo for reuse. Our testers loved this mess-free activity. Great for quiet time or travel (car and airplane windows make the perfect canvass). The kit includes a very generous supply of Bendables in ten vibrant colours, and a very useful step by step tips and idea book.
