Heard so much about the use of bamboo in different product, we are not done yet, because another eco-product made from bamboo is now again being made. This time around, it is a little useful thing called the ruler, and the product was named bamboolarule. Dsigned intentionally for an arthritic user, the bamboolarule has lovely design and looks like it is a long lasting object. Made from bent laminated bamboo, the bamboorule allows fingers underneath for easy pick up. Preschoolers will definitely enjoy its flexibility and will not break a rule anymore. This can be a perfect supply for your pre-schoolers.
