Whoppers! Made by Quicknit, says 3/4 which much be inches. Giant sized plastic knitting needles, they are 41 cm long - matchbox in 2nd photo gives an idea of size.
Sydney Metro postcodes are a max. postage rate of $12 (up to 500g $9 or less), pretty much no matter how much you buy!
Please convo me too with any questions you have, or if you're wanting to buy more than one item. I can edit the listings tailored to you in your favour. I love to combine shipping where possible and save YOU money. I.e. if the post rate is for up to 500 g and combined it weighs up, I'll send multiple items for the same price.
