In other reviews it was said that there was difficulty in adhesive strength, so I bought it while playing hard. We are using it for cardboard sealing of chinese cabbage, onion, cabbage (content of 10 ~ 20 kg). There are somewhat adhesive strength points, sometimes it does not cling to it when the corrugated cardboard is wet in rainy weather, but it can be used without any problem at the time of shipment. I am pleased that the price is cheap (I never made it cheap!). I would like Monotaro to definitely keep pricing unchanged or lower by price cut!
