Kobe Franz These are the pots for the Magic Pot Pudding. Set of 4, with the box included. They have been washed, dried, and wiped with disinfectant wipes. How about using them for making pudding, sweets, etc.? Also, they look cute like octopus pots when placed in a fish tank! They are also recommended for dioramas and plastic models! You can also use them as planters for mini cacti, etc., and they are cute just by displaying them in a row! Diameter of the pot's opening... approx. 4cm Widest diameter of the pot... approx. 5.5cm Height... approx. 5.8cm Thank you very much. Material... Ceramic
