Glass bottles were great, they came on time, packaged very securely (important as they are glass) but with entirely paper easily recyclable packaging. They are very good quality, don’t scratch or brake easily (and I have dropped one and I carry them in metal baskets). The opening of the bottle is big enough that it’s easy to fill with water without a funnel, and so that antibacterial spray tablets fit through. The spray bottle top is good, doesn’t feel cheap and has a feature so that you can close it it and make it safe to transport, as none can be accidentally sprayed, that is also marked with little signs on the spray lid too so you don’t have to guess which way to turn it. All round great product. Great way to minimise plastic without changing your routine at all.
