What Kinds of Products Are a Good Fit for Click Post?
Have you ever looked at one of your products and wondered, “Can this be sent by Click Post?”
Click Post’s flat 185-yen nationwide price is simple, but that does not mean every product fits. There are strict size and weight limits, so you need to confirm whether your products actually match the service before building your workflow around it.
I have used Click Post as my main shipping method for three years, shipping more than 2,200 small handmade products such as TRRS cables and resin keycaps. Early on, I even had packages refused at the post office because they ended up thicker than 3 cm after packing. Those mistakes taught me very clearly what kinds of products work well with Click Post and what kinds do not.
This article organizes that experience into a practical guide.
Click Post Size and Weight Requirements
First, let’s confirm the core conditions for a package sent by Click Post.
| Item | Condition |
|---|---|
| Long side | 14 cm to 34 cm |
| Short side | 9 cm to 25 cm |
| Thickness | Up to 3 cm |
| Weight | Up to 1 kg |
| Price | Flat 185 yen nationwide |
If the package fits into an A4-type envelope and stays within 3 cm thickness and 1 kg, it can generally be shipped by Click Post. It is delivered to the mailbox, so the recipient does not need to be home, and the tracking number helps reduce “Has it arrived yet?” messages after shipping.
Examples of Products That Work Well with Click Post
Accessories and jewelry
Earrings, necklaces, bracelets, and similar items are usually small and light enough to fit well within Click Post’s limits. Even with cushioning material, it is often easy to stay within 3 cm thickness.
Stickers and labels
These are classic Click Post items. They are flat, light, and easy to protect with backing paper inside an envelope, usually well under the thickness limit.
Cables and electronic parts
The TRRS cables I sell for keyboards fit well in A4 envelopes when coiled, and usually stay within about 2 cm thickness after packing. USB cables, connectors, and other compact electronic parts are similar. Because cables are flexible, they are also easy to shape for packing.
Resin keycaps and other small handmade items
A resin keycap often weighs only 10 to 20 g. Even with protective wrapping, it usually stays within 3 cm. The main caution is multi-item orders. In my own shop, orders of five or more keycaps sometimes exceeded the thickness limit once packed, so I switched those cases to another method.
Smartphone cases and screen protectors
Thin phone cases and screen protectors are also common Click Post items. Bulkier folding cases can exceed the thickness limit, so measure the packed item rather than the product alone.
Fabric accessories, handkerchiefs, and pouches
Thin fabric items often fit if folded neatly. Bulkier pouches or soft goods with thicker materials may still exceed 3 cm, so they need an actual measurement after packing.
What Does Not Fit Click Post Well
Click Post is useful, but it is not universal. The following kinds of products usually need another shipping method.
| Condition | Why it is a poor fit | Alternative |
|---|---|---|
| Over 3 cm thick | Exceeds Click Post limit | Letter Pack Plus, Yu-Pack |
| Over 1 kg | Exceeds Click Post limit | Letter Pack Plus or Yu-Pack |
| Fragile or high-value item | No compensation if lost or damaged | Yu-Pack or courier service |
| Needs cash on delivery | COD not supported | Courier delivery |
| Needs signature on receipt | Mailbox delivery only | Face-to-face courier delivery |
The lack of compensation is especially important. If a package is lost or damaged, Japan Post does not provide reimbursement for Click Post. For expensive or delicate items, a compensated shipping method is usually the safer choice.
Price Comparison with Other Shipping Methods
How attractive is Click Post’s 185 yen in practice? Here is a simple comparison.
| Shipping method | Price | Tracking | Compensation |
|---|---|---|---|
| Click Post | 185 yen | Yes | No |
| Standard mail, up to 50 g | 140 yen | No | No |
| Standard mail, up to 150 g | 270 yen | No | No |
| Yu-Packet, up to 3 cm | 360 yen | Yes | No |
| Letter Pack Light | 370 yen | Yes | No |
| Letter Pack Plus | 520 yen | Yes | No |
For very light items under 50 g, standard mail can still be cheaper. But among tracked shipping methods, Click Post is one of the cheapest options available.
In my own case, most products were heavier than 50 g, so Click Post offered the best balance of price and tracking. The presence of a tracking number alone made a visible difference in reducing customer questions.

How to Confirm Whether Your Product Fits Click Post
- Pack the product for real: use the envelope and cushioning you would normally use
- Measure the thickness: confirm that the packed item stays within 3 cm
- Weigh the packed item: make sure the total stays within 1 kg
- Confirm the overall size: ensure it fits within 34 cm x 25 cm
Do not judge only from the unwrapped product size. Cushioning material can easily push a 2.5 cm item past the 3 cm limit. That happened to me early on, and since then I always measure after packing, not before.
Common Questions
Q. Can I send food with Click Post?
As long as it is not prohibited content and does not require refrigeration or freezing, some shelf-stable food items may fit if they meet the size and weight rules. Perishable goods are not suitable.
Q. Can I attach a fragile sticker?
You can attach one, but Click Post is still a mailbox-delivery service. There is no guarantee of special handling just because you label the package as fragile. Proper packing matters more than the sticker.
Q. Can multiple products be combined in one Click Post package?
Yes, as long as the final package stays within the size and weight limits. For example, several stickers and one keycap can often be combined into one shipment.
Q. How many Click Post shipments can I process at once?
With bulk application by CSV, one upload is limited to 40 shipments. If you exceed that, split the file and upload it in multiple rounds.
Conclusion
Click Post works best for small and lightweight products that remain within 3 cm thickness and 1 kg. It combines low nationwide pricing, tracking, and mailbox delivery, which makes it especially attractive for accessories, stickers, cables, and other small handmade products.
Its main limitations are the lack of compensation and the inability to handle thicker, heavier, or more delicate items. As long as you understand those tradeoffs, Click Post can be a very strong part of your daily shipping workflow.
