If you want to buy Ron Weasley's wand then you will be happy to know that there are several version's of his wand to choose from. Below you will find a traditional version, interactive version, a toy version, and more.
Ron was one of a small number of characters to have more than one wand. The first wand he had was a hand-me-down from his oldest brother Charlie. I'm sure that you remember how that wand broke when Ron and Harry Potter crashed his dad's flying car into the Whomping Willow at the beginning of their second year at Hogwarts.
The wand seen below is Ron's second wand, and the one most often associated with him. He was given a new wand some time before his third year at Hogwarts. We aren't sure if the wand chose Ron or if his parents chose it for him, but it seemed to work very well for him, and he used it until it was taken from him by Snatchers in the final story.
Wand Wood
Ron's second wand (the wand most commonly associated with him) was made from the wood of a willow tree. That seems a bit ironic given that his first wand was destroyed by a Whomping Willow tree!
According to wandlore, wands made of willow work best when matched with a witch or wizard who is insecure. I'm sure you'll agree that Ron was riddled with insecurities from the moment we met him at King's Cross station.
Wand Core
The core of Ron's second wand was a unicorn hair. Wands with unicorn hair cores are known to be very reliable and the least likely of all cores to be turned to the Dark Arts.
Interestingly, wands with unicorn hair cores are sometimes prone to fits of melancholoy. Ron had his second wand with him when he, Harry Potter, and Hermione Granger were looking for Horcruxes during Harry Potter and the Deathly Hallows. Ron was prone to fits of melancholy brought on from wearing the Horcrux necklace that they were unable to destroy. I can't help but wonder if his wand also suffered from depression during this time...
Wand Length
14 inches
Wand Design
Ron's first wand was very plain but this one has quite a bit of character. Honestly, I'm torn on what it looks like. On one hand, it appears to be a somewhat gnarled wooden stick that was roughly carved, with the outer part of the wood untouched on the handle. On the other hand, it reminds me of a very old bone that has been yellowed with age. Regardless, it is interesting to look at and looks like it would be comfortable to hold in your hand.
Ollivanders Wand
There are two versions of Ollivanders wand for Ron. The first image below is the one you can buy if you are fortunate enough to go to Universal Studio's Wizarding World of Harry Potter. It comes in one of Mr. Ollivander's boxes that is lined with a soft material to keep your wand safe for years to come.
The second image is of the version made by the Noble Collection that does not have a nameplate. It is also in an Ollivanders box but the box in the second image is more like the boxes from the films.
Interactive Ollivanders Wand
Interactive wands are Ollivander wands, but unlike traditional Ollivander wands, these can be used to cast magical spells at the Wizarding World of Harry Potter in Universal Studios. There is an interactive version of Ron Weasley's wand that looks identical to the one seen above, except at the tip. I wrote about interactive Harry Potter wands if you are unfamiliar with them. You can read about them here.
This version of Ron's wand is sometimes hard to find online. If you don't see it at either Amazon or eBay then be sure to check back at both sites every so often since you never know when it will be listed for sale.
Here is a video that I took of my daughter as she used her interactive wand to cast a spell. FYI - This is one of the hidden spell locations...
Some browsers prevent videos from playing so if you are unable to watch the video then I recommend that you try again using a different browser (i.e. Google Chrome or Opera)
Noble Collection Wand
The Noble Collection version of Ron's wand includes a different box than the Ollivanders box and a removable name tag. Noble Collection boxes are lined with a soft material to help protect your wand and have each character's name on the lid of the boxes.
Illuminating Tip Wand
Want to cast the Lumos spell? Then you need a wand that has light at the tip! I've seen a couple versions. The one seen below appears to shoot light from the tip, and another one I've seen lights up at the tip like a dim lightbulb.
Rubie's Toy Wand
I would argue that most of the wands on this page are meant for adults, and at least one is a collectible item. So, that might make you wonder, where does that leave children who want to pretend to be Ron? Fortunately, there is a wand that is meant specifically for children and is meant to be played with. The wand seen below is made of durable plastic and will stand up to years of spell casting.
Custom Wands
The last type of wand is a custom made one. There are several sellers on Etsy who have made their own versions of Ron's second wand. Some even come with a custom Ollivanders box.
