Silicon Cover SSACK MintA6

This all-new cover design debuts this year for a unique silicon option. The soft, elastic silicon resin feels clean and pleasant to the touch. The cover wraps around your planner book and snaps shut with a magnet for a perfect fit around your usual Hobonichi Planner, or even the skinnier six-month Japanese “avec” version book. The cover includes a small pen holder designed to fit a pen clip, incisions to hold cards, one bookmark, and a side-flap to keep your place. The refreshing mint color of this cover is fun to match with all kinds of stationary. Feel free to branch out and give this all-new cover design a try.

Please Read

In order to provide you with the most satisfaction for your product, we've compiled a list of warnings, potential issues, and tips to keep in mind for this particular product. Please be sure to read this information carefully before placing your order.

About the metal sheet inside the cover

The SSACK cover includes a hidden metal sheet used to attract the magnet in the flap when closing the cover. The metal sheet is kept very thin to make the cover more comfortable to use, so strong pressure may cause the sheet to bend or rip through the cover. Please handle with care. Please also note that the metal of the sheet may cause discoloration of the cover over long periods of time.

Black dots on the cover

Small black dots may be visible on the cover material. Please note that these are unavoidable occurrences during the silicon material’s manufacturing process.

Please keep away from sharp objects

Please keep the cover away from blades and other sharp objects to avoid rips and damage.

Cleaning a dirty cover

If you feel the surface of your cover has become dirty, we recommend wiping it with a clean cloth or sponge dampened with diluted neutral detergent and then wiping the cover dry. Because the cover includes hidden magnets and a metal sheet, please do not soak it in water. Please note that the silicon material of the cover easily attracts dust..

Storing your cover

Please keep your cover out of direct sunlight and away from heat sources as it may result in discoloration, distortion, or deterioration.

About the smell of silicon resin

The cover material is processed to remove the smell, but some of the smell may linger in the very beginning. Please use the cover as usual, and the smell will fade over time.

Warning about magnets

This cover closes using magnets hidden in the outer flap. Putting this magnet near credit cards, IC “smart cards” or certain types of watches may erase the data, so please be careful of how you use and where you put your cover.

About the pen holder

The pen holder is designed to hold the clip of a pen, so please note it does not work with pens that do not include a clip.
