@Altay.Oro, based on this article from Alagobox, I believe they are called transparent blister liners/trays.
Does anyone know where to purchase blister trays like the ones used by Sugoi Sweets (or do these trays fall into the "custom-order" category)? I can find more "traditional-looking" inserts but am having a really hard time finding transparent, round blister trays. I like the minimalist look of these trays. @Tiffany B linked to these by A Specialty Box, but they don't look quite as clean as the ones used by Sugoi Sweets (and it's hard to tell what the bottom insert looks like from A Specialty Box's images).
