We love the feel of natural cotton canvas, but it needs to be protected from the elements. Using feedback from their customers, YKRA created a wax for waterproofing their products. YKRA's MAGIC BEESWAX is a naturally impregnating wax for waterproofing canvas products. Handmade in Hungary from beeswax and paraffin according to traditional recipes. Keep in mind that Magic Beeswax shouldn't be used on white or natural colour canvas, as it could potentially discolour the product's colour. How to impregnate your backpack:1. Gently rub the wax on the outer canvas parts, making sure that it is evenly distributed2. Use a hairdryer on a mild setting to warm up the wax. Letting the canvas soak it up!3. Test to make sure you have applied enough wax, and the water runs off. If not, repeat steps 1 and 2!Learn more about waterproofing your YKRA products here.
