Material: Acrylic Size: 18cm long x and the flamingo is 4cm wide (7.08 inches x 1.57 inches) Quantity: This article includes 1 stirrer Treatment: Natural, Unfinished Shape: Stick Uses: for your drink or decoration... Because it's made of acrylic (plastic) you can use the sticks on your drinks without any problem. I will recommend to wash them with a bit of soap but not on the dishwasher to avoid any scratches. You can also change the colour of the acrylic, I have many colours on stock but please ask me first so we can talk about the options. The sticks are made out of recycled acrylic from local UK business.
