The Ultimate Competition Tacky Atlas Tacky Strength Grade III has been formulated to provide the strongest stick in our range. It is ideal for the heaviest stones and competition use. Warning: This tacky can require some work to get it warm and ready. However this depends on the local temperature. Tacky will also reduce the load/stress on fingers, hands and biceps which can reduce the risk of injury and tendinitis. -Not suitable for cold conditions! -Handmade in the UK Available in 5.1oz (150ml) or 8.45oz (250ml)
