AI'm looking for sleeves that slide over plastic cupcake clamshells? I've seen them before but can't locate a place to purchase them!!! Please help!!!

You could just measure around your clamshell and then cut a strip the right size and tape it on the bottom...

That way it contains the information that you wish it to...

AThat's is true, however this place I could have sworn had them where there was a cut out to still see the product. I'd rather order them than cut them myself.
