The Eco rainbow straws are great to combine with many mottos. The 20 drinking straws, striped in pastel shades, are 20cm long and have a diameter of 8mm . So whether it’s the juice for a children’s birthday party with a unicorn motto, the tequila sunrise for a summer party, or the strawberry punch for a birthday , these straws always work. It’s even better that the product and packaging are 100% recyclable and biodegradable .
