Owner needs to stick to selling tobacco instead of accessories. He started an argument with me because I asked him if a piece was made of quartz or regular glass. His sign said it was glass, the price indicated it was glass, yet he insisted it was quartz. I asked him how long the product would last and he claimed that if I used it everyday it might only last for a few days before breaking. That's completely unacceptable and at $12 for a quartz nail it's very obvious this product came from China and probably cost him $1 a piece or less. Avoid buying anything here. Cheap low quality products and rude argumentative owner.
