The 2 oz bottle is made of low density plastic and is very easy to squeeze. It is a boston round style, which has a curve from the bottle reservoir through to the neck, allowing material to easily flow out from the top. The luer lock cap threads onto to the bottle, and then accepts any luer lock needle. Ideal for flux, solvents, adhesives and solder mask. 10 bottles and 10 caps come in each bag ordered
