AA Battery Box with Spring

Practical AA battery box ("single" size) with an integrated spring for secure contact. Perfect for simple experiments and educational projects with children. Facilitates connection of alligator clips. Some products allow ordering multiple units without increasing the price—please send a message. Price is non-negotiable! Sales are only conducted in person in the Barreiro area and surrounding regions. I can ship by mail, but only with advance payment via MB Way, and shipping costs are borne by the buyer. #BatteryBox #AA batteries #Experiments #DIYProject #EarlyChildhoodEducation #ElectronicComponents #ScienceForKids #Gadget #Portable #Tool
