Hello: There are several places to go 1. Large food market. Dalian aquatic products market. There are many packaging shops. The cheapest is the big food market, which sells packaging. Don't go to big stores, brand-name packaging stores, expensive stores and ordinary stores! The price depends on what size you want. The average price is about one size lower than that of 2 yuan. There is also an incubator. The wholesale price of the smaller size is about five to eight yuan. It is very important to bargain in the big food market. You must be able to talk about it. You have to lower the price to get a cheaper one. Finally, I wish you all the best! I'll contact you later!
