Please be aware that although the stated sizes of boilie are usually accurate, the finished product can vary plus or minus by approximately a millimetre. Whilst we make efforts to produce the best boilies we can, the shape of the finished round boilies will not be a geometrically perfect sphere. Please do not order this product if you require an absolutely spherical bait for some reason. The Devil Squid is purposely designed for flowing water, so will continue to leak off food signals for several hours. We advise casting with a new bait at least every 4-6 hours.
