GLM has been used in baits for many, many years and is a must have in any good fishmeal boilie.
As with all the Sticky Pure Natural range, the usage isn't limited to simply including in boilie mixes and hookbaits. GLM Extract is another fantastic additive for any pellet, spod or PVA mixes - and again can easily be dissolved into any liquid to greatly increase the natural attraction. 100g tub.
Due to the natural nature of the GLM Extract, there is no cap on the inclusion rates, however Sticky suggest a minimum of 50g per KG (or 5%).
