Don't forget to take care of heatstroke prevention this summer with your favorite my bottle.

A my bottle is a wonderful companion while working remotely, studying, or out and about, letting you enjoy a sip of your favorite drink whenever you like. Having one on hand means you can always drink at just the right temperature, and when you're out you won't need to hunt for a convenience store or worry about creating trash. Bringing your own bottle to your favorite coffee shop is also a small way to help reduce waste.

For cold drinks, the insulated bottle from Black+Blum boasts excellent functionality, keeping beverages at temperature for 24 hours. Even with cold drinks inside, there's no condensation, and the bottle seals so well that you never have to worry about it sweating in your bag or leaking and getting your other belongings wet.

When you want to concentrate on work or study, it's convenient to prepare your drink in a my bottle beforehand—that way, whenever you feel like taking a sip, you can simply reach for it without having to leave your seat.

It's said that the body tends to become dehydrated not only during the day but also while sleeping. Keeping a bottle handy so you can drink water before bed and upon waking is helpful, and it's also reassuring to have one nearby so you can quickly give your child something to drink if they wake up in the night.

Black+Blum's insulated bottle features a stylish design in which the cap is connected to the body with a leather strap. This makes it easy to carry without having to grip the bottle firmly with your hand, and since the opened lid stays attached, it's easy to drink from while you're out.

Let's take a look at the amount of water needed for heatstroke prevention in terms of bottle capacity.

It's said that aiming for 1.2 liters a day, taken in small amounts frequently, is ideal. In particular, be mindful during the summer months to drink upon waking, before bed, before and after (and during) exercise, before and after bathing, and before you even feel thirsty—keeping an eye not just on yourself but on your family as well.

Looking at that target amount in terms of Black+Blum bottle capacities: the S size holds the equivalent of one 500ml PET bottle, meaning 2.4 of these bottles covers the daily water intake needed for heatstroke prevention. The L size holds 750ml, so 1.6 bottles would be the daily target. Using a my bottle also makes it easier to get a rough sense of how much water you've had so far, which is a nice bonus.

A my bottle is something we hope you'll use every day, including for heatstroke prevention. To go along with the new colors of the Black+Blum insulated bottle, we've also prepared a brush set to help you keep it clean hygienically for continued use.(*The brush is not sold separately.)

From a long-established Swiss brush maker

When it comes to bottle-cleaning brushes, both sponge-type and bristle-type have their own merits, but with either material, what matters is the length, the shape of the head, and whether it can be hung up to dry. This brush is one that has arrived at a design clearing all these conditions, making it a recommended care item for anyone who loves using a bottle.

[ Strengths and points to note by material ]

For sponge brushes

◎ Gently cleans without scratching the interior

△ Durability and quick-drying performance are somewhat lacking

For nylon-type brushes

◎ Cleans dirt well

◎ Durable and quick-drying

△ Depending on the material, it can scratch surfaces

The brush from Ebnat that we're introducing here has a thin, long handle, making it ideal for cleaning tall, narrow-mouthed bottles like a my bottle or water flask. The head also has bristles, so it's convenient for cleaning even into the corners thoroughly.

This Ebnat brush has been designed with a handle length and a unique bristle structure that allow for simple, efficient bottle cleaning. Some might think the amount of bristles seems remarkably sparse, but this is the shape that this long-established brush maker has arrived at.
