The Karpela Container can be used in various fishing disciplines and in various ways. For example, you can use it to attract fish with a thick gel, or live bait like (blood) worms and maggots. Pasta, corn, or boilies can also be used. These bait containers consist of two plastic halves that you twist together to seal. This prevents crayfish, for example, from getting a grip on your bait. They are available in various colors and with holes or grooves. They are packed in blister packs containing four pieces, divided into 1 x 10 mm, 1 x 14 mm, 1 x 18 mm, and 1 x 22 mm.
