Review on 15-Pack 4 oz Empty Plastic Squeeze Bottles with Red Tip Caps - Ideal for Arts & Crafts, Glue, Multipurpose Use - Includes 15 Chalk Labels and 1 Funnel by Amber Perez

These bottles are easy to fill with the funnel provided. They can be reused if you like, I personally use mine to paint and just fill up with the same color when they run out. Where the liquid comes out is a red valve at the top that lets you control how much comes out at once and you can remove this for easy refilling. The bottles are transparent and you can easily see what's inside. They are perfect for glue, paint and any type of liquid you need to determine how much comes out and what they are perfect for. The bottles are BPA-free and very well made. It was exactly what I was looking for when looking for paint containers.
