Sugru by tesa - Deformable Universal Adhesive, 8 x 3.5g, Black - Versatile Knead Eraser - For Repairing, Gluing and Fixing without Drilling

Moulded bigger buttons on my Sax, worked a treat.

Incroyable repar tout, super pratique, toujours en avoir a la maison Simple d'utilisation

Formbarer Silikon für Kleinereparaturen bestens geeignet, Lagerung im Kühlschrank empfohlen, aber zeitlich begrenzt.

Upon receipt, I saw that the product comes with a "use by" date (mine was good for around 7 months; storing unused packs in fridge is supposed to increase this). Other than this, it seems to be a decent product, as it forms a good, semi-rigid, seal quite easily (updated review to 5-stars to reflect this-it really seems to work as advertised)!

Sugru moldable rubber Used for cable reinforcements many times before. Quality is fine. The durability of the final product is fine. It's very easy to use. You can't complain about it providing you follow the instructions. Keep it in the fridge when sealed and it will last a little longer. It goes off when open after about 24 hours. Shelf life I purchased was about 9 months but you get varying dates. You don't really get in a mess with it, providing you take adequate precautions. Make sure you have clean hands as sometimes it will not stick to the product and instead to your hands Easy to remove from your hands if this is the case
