These plastic bottles are great for adding fun effects to mixed media and papercrafting projects. The pump-spray bottles are great for misting. Each bottle in the two-pack can hold 2.6 oz. and has a screw-off pump-spray top as well as a plastic cap. The writer/glue bottles can hold 2oz each and come with a screw off plastic nib tip that can be cut to provide a wider opening and a plastic cap that snaps on over the tip.
