This is a set prepared for crystal making in August 2025. Most items are from 100-yen shops and have been used, except for the petri dishes and pipettes. The petri dishes are half-used, with 5 pieces remaining. ※ This does not include bismuth chips, but they are sold separately. Alum is also currently listed. ※ Please note that due to shipping costs, the items will be simply packaged and shipped in a waterproof bag.
