Instead of foil, I use the particularly thin packing tape from Aldi Süd. Unfortunately, the packing tape is only a promotional item and, according to my research, can only be obtained from Aldi Süd at the time of the respective promotion. If anyone finds a similar packing tape or knows where Aldi Süd packing tape can be obtained elsewhere. Please info me.
cutter knife
I use a special cutter to cut off the silicone hoses. It is an Olfa 2124430049 AK-1 Messer Art Knife (with 25 blades). The slanted shape of the blade is perfect for cutting hoses straight.
In principle, any good household scissors can be used. You really just have to cut well. I use the REMOS household scissors, universal scissors, pointed-round, straight cutting edge, 12 cm, stainless steel
