These bracelets are intended to be for the Drarry (Draco/Harry) fandom and shippers - hence the Gryffindor red and Slytherin green colors coming together to meet in the middle with a silver heart - but anyone is welcome to interpret them in any other way, since they aren't specifically labeled for Drarry lovers only. I run a Drarry based blog, so that's where I got the inspiration for these.
You could also use them as Harry Potter friendship bracelets if you and a friend are sorted into the two rival houses but still want to show off your friendship with two of your own.
(For example, I'm a Slytherin and my cousin is a Gryffindor, so we have these matching bracelets!)
All of the bracelets are handmade with nylon thread by me and take about 3-4 hours to make. I made sure that they are all adjustable to fit just about everyone, so there should be no worry for length or sizes, but you could of course message me if you have any specific requests or problems with the bracelet and I will be happy to help.
There's a very limited quantity of these bracelets, but I will definitely make more if requested.
