A nipper or tile nipper (like a pair of scissors or pliers) is a tool used to "nip" or remove small amounts of a hard material, such as pieces of a tile, which needs to be fitted around an odd or irregular shape.
I have used this Cornertape many times when taping & jointing, it is much sturdier than more well known brands, I can always achieve nice sharp and straight corners, It is far superior to any other Cornertape I have used for quality and price, excellent tape and excellent value for money.
The service was great, I contacted the store by chat as I needed 5 units of the same tool while online, there was only one left. They managed to source the rest and post them the same day.
Highly reliable.
