I have this little set of Halloween cookie cutter which I purchased from Lakeland.
The set consists of 4 little Halloween themed cookie cutters; a witch, a ghost, a bat and a pumpkin.
They are made of orange plastic, I've long since thrown the packaging away so I can't remember if they are dishwasher safe or not, but I do put mine in the dishwasher, only on a 35 degree wash though.

They are fairly sturdy and easy to use, the tops of the cookie cutters have a slight lip on them to make them easier to handle. especially when lifting them back up after you have stamped your cookie out. I have had no problems with them at all, they cut out perfect creepy cookies every single time. I do find that if you are using a particularly sticky cookie dough then it helps if you flour the edges of the cookie cutter first before you stamp your cookie out.

I've obviously used them for cookies, I've also used them to stamp out shaped brownies once the tray of brownies is cooked, I've used them to stamp out shaped sandwiches, I've even used them to stamp out shaped pancakes.

They were a great little purchase and they have lasted really well. I reckon that I'll be using them for years to come.
