6 month old male rats with cage and accessories

I am looking to rehome my daughters new pet rats due to realising that I have severe allergies and am unable to care for them. The boys are approximately 6 months old and have both become very curious but have not been properly handled. Hot Chocolate (black rat) is very energetic and is more curious and brave than his brother, Bubblegum. Bubblegum is very gentle and can be timid but is starting to come out of his shell. I have spent well over £300 in the 2 months of having them and am just looking to get some of the money back and find them a home with someone who is able to give them the time and patience they need to be handled. The boys will come with the cage, all toys and accessories, pet carrier as well as food and lots of treats.
