Solmates

An empty, refillable container with a roll-on ball, designed for you to fill with your own sunscreen or cream. It does not come with sunscreen in it.

The roll-on applicators come in 50ml and 100ml, and there is a 25ml screw-top pot for smaller amounts. All of them have a removable base so you can refill and wash them properly.

No. Solmates sell the container only, which is the point of the brand: you fill it with the sunscreen or cream you already use and trust.

That also means the SPF, the expiry and the storage rules are whatever the product you decant says on its own bottle.

The 50ml applicator is the everyday one, 7cm high, which fits a handbag, a school bag or a glovebox. The 100ml is 10.5cm high and suits a family beach day or a week away.

The 25ml pot is 3.5cm high and flat, for a small amount of zinc, balm or moisturiser, or for tablets and earrings. The pot trio gives you all three colours, which is the easiest gift in the range.

Unscrew the base, squeeze or spoon your sunscreen in, and screw the base back on. The roll-on ball stays where it is.

Thick creams and lotions work well. Anything runny and liquid does not, because it will find its way past the ball.

Unscrew the lid and the base, scrub all the parts with detergent and a brush, rinse, and leave everything to dry completely before you refill it.

Do not try to pull the roller ball out. Wash it before you change from one product to another, and let it dry fully, because trapped water will thin whatever you put in next.

Yes, within the usual carry-on liquid rules. The 100ml applicator has its capacity marked on the body, which makes the 100ml limit easy to demonstrate at security.

The 50ml applicator and the 25ml pot are both comfortably under the limit.

Certified recycled plastic and mineral talc, with a thermoplastic roller ball and a silicone tether, made in Sydney from 80% certified recycled plastic.

Because the plastic is recycled, the colour and finish shift slightly between batches and you will see the odd speckle or fleck. The brand treats that as the point rather than a fault.

Yes. Moisturiser, after sun, zinc, hand cream, balms and gels all work, and the 25ml pot is regularly used for tablets, snacks or jewellery.

They are meant for carrying a product and using it over a short period, not for long-term storage, so decant what you will get through rather than filling one and forgetting it.
