Our series numbers are just a quick way to match bases & lids. Matching series numbers = matching products* e.g. Any 79 Series cup will fit any 79 Series lid.
*Please note: the 185-Series clear PLA lid fits all 185-Series bases, however the 185-Series paper lid only fits 185-Series paper bases.
But how do we come to the specific series numbers? These are usually based on product width (e.g. 79 Series = 79mm rim, 185 Series = 185mm rim)
