Ordered these for my sons birthday party and they are so cute. Per other reviews, I opted to not bake directly in the cups (for talk of discoloration,etc.)- however, this did not work out so well for me. When I placed the cooked cupcakes into the Thomas liners it looked awful and very amateur. Perhaps you could place another cupcake liner inside of the Thomas liner and bake it that way and maybe it would work?Anyway, I did end up baking a couple of vanilla cupcakes in the Thomas liner and they came out perfect! Wish I'd done it that way from the beginning. Oh well!Also, these were cheaper at my local party city FYI.Very cute cupcake baking cups. Like most cups, they discolor when baked. Would have been nicer if they were foil lined, but very nice print and colors even with the darkening with baking. Fit with the theme of the party perfectly, and fit with other Thomas accessories bought from local stores.These baking cups work exactly as expected. They are a standard size. The print is bold and colorful, and it does not fade when baking. However, these cups are NOT grease proof, so I recommend buying twice as many as you need and doubling up on the cups...especially if you plan to make chocolate cupcakes. The print on the inner cup will be obscured a bit as they absorb the grease from the cupcakes (or if you use cooking spray on them), and the outer cup will remain vibrant as ever.Like: decorationsDislike: oil shows through the bottomThese are so cute and great but due to packaging came a bit smashed. Once we baked them they were fineThey were for my grandsons bday part and were very cute!!As others say the cups do turn a little dark but I don't see how it's a problem or why people complain about it. Considering you are baking them in an oven lol. Do not let this factor into your decision on getting these lines though. You will no be disappointedCute, but you can't see the design once they've been baked in. So do yourself a favor: bake the cupcakes in cheap, plain baking cups and then slip these over after they're done.I bought these for my Godsons 3rd birthday, and he was obsessed with them. Brilliant quality. Only reason i haven't given it a 5 star rating is because at the time i ordered it didn't state anywhere how many id get in a pack. I needed 24. I assumed id get either 12 or 24 in a pack as they were character. So i ordered 2 packs. Theirs actually 50 in a pack so how i have 100?!Bright colourful Thomas pictures. My 3 years old grandson, whose is Thomas mad, loves using these in our baking sessions.added finishing touch to first birthday Thomas themed partymade a little boy happy but quite expensiveflimsy
