リスナー情報コーナー(水) 買ってよかった！イチ押しアイテム図鑑:個人情報保護スタンプ ローラーケシポン 箱用オープナー(プラス株式会社)
On the Wednesday segment 'Best Buys: My Favorite Item Encyclopedia,' listener Mei-san, 53, from Kanagawa Prefecture, introduced the PLUS Corporation 'Privacy Protection Stamp Roller Keshipon Box Opener,' a two-in-one stationery tool that combines an ink roller for blacking out personal information with a built-in box cutter. She demonstrated both functions live in the studio, prompting host Sū-san (スーさん) to marvel that the text was 'almost frighteningly invisible.' The item retails for ¥1,100 and was registered as the 137th entry in the encyclopedia.

What this episode answers
What kind of product is the Keshipon Box Opener?
It is a stationery item that combines an address-concealing roller stamp with a small built-in box cutter in a single body; twisting the cap at the bottom exposes an inked roller that, when rolled over text, hides it completely using a proprietary ink that bonds even to glossy paper and overwrites the original characters with a randomized ten-letter alphabet sequence.
How effectively does it conceal an address? What happened during the in-studio demo?
Sū-san tested it on printed text on an envelope in the studio and confirmed the text became completely unreadable; she also tried it on a glossy address label from an overseas parcel and the address vanished instantly, leading her to comment 'it's almost frighteningly invisible.' Even on thin paper that might show through, rolling from both sides eliminates the text in about one second.
Why did Mei-san start using this product?
Mei-san's nails had weakened with age, making it hard to peel shipping tape, and glossy labels on overseas parcels were especially difficult to remove, leaving her worried about discarding parcels with personal information still visible.
Who is it especially suited for, and in what situations?
Sū-san identified four types of users it suits particularly well: people who receive many parcels every day, households where family members won't process the personal information on cardboard boxes, people struggling with hard-to-remove glossy labels on overseas deliveries, and small offices that bought a shredder but might have managed fine with this instead.
What are the price, color options, and assigned character in the encyclopedia?
The suggested retail price is ¥1,100; the staff purchased it online for ¥652 including tax, and depending on the site it can be found for under ¥500. Multiple colors are available — the one in the studio was yellow-green. The assigned character for the encyclopedia entry is 'ケ' (from Keshipon), and it was registered as the 137th item.
The Listener: Mei-san, 53, from Kanagawa Prefecture
This week's Wednesday 'Best Buys: My Favorite Item Encyclopedia' segment heard from Mei-san, a 53-year-old listener from Kanagawa Prefecture who describes herself as a silent listener but found the courage to share one of her absolute favorites. Her submission became the 137th item entered in the encyclopedia.
What Is It? Two Functions in One Tool
The PLUS Corporation 'Privacy Protection Stamp Roller Keshipon Box Opener' (プラス株式会社「個人情報保護スタンプ ローラーケシポン 箱用オープナー」) does two things.
The first is an address-concealing roller stamp. Twisting the black cap at the bottom of the body reveals an inked roller; you simply roll it across an address label and the text disappears. The proprietary ink is formulated to adhere even to glossy paper, which conventional inks have historically struggled with. The concealment method is also cleverly designed: rather than drawing a plain line over the text, the roller overwrites it with a randomized sequence of ten alphabetic characters, making it far harder to read the original than a simple strikethrough would allow — the position of the underlying letters becomes indistinguishable.
The second function is a small cutter blade built into the top of the body. It slices cleanly through packing tape and adhesive tape on boxes.
Why Mei-san Bought It: Weak Nails and Stubborn Labels
Mei-san's problem was threefold. First, her nails had weakened with age, so when she tried to peel shipping tape she could only get a few millimetres up before getting frustrated. Second, parcels from overseas often come with glossy address labels that are particularly resistant to peeling — she found herself worried about throwing boxes away with her personal information still clearly printed on them. Third, there was simply no easy way to handle both problems with a single tool.
The Keshipon Box Opener solves all three at once: when a parcel arrives, she rolls over the address label, then uses the built-in cutter to slice open the tape — start to finish without stress. As Mei-san put it, 'I can open it without feeling any of that frustration.'
In-Studio Demo: Sū-san Says 'Almost Frighteningly Invisible'
Sū-san (スーさん) tried the roller on printed text on an envelope right in the studio and confirmed that the characters became completely unreadable. 'I have no idea why it disappears, but it disappears,' she said, visibly surprised. She then tested it on a glossy overseas-parcel-style label, and even with the label still stuck to the surface the address vanished in an instant. Her verdict: 'It's almost frighteningly invisible.'
For anyone worried about thin paper showing through from the back, rolling the stamp from the reverse side as well takes about one second and eliminates any chance of the text being read.
Sū-san outlined the people most likely to benefit: those who receive multiple cardboard boxes every single day; households where no matter how many times you ask, family members just won't deal with the personal information on boxes; anyone battling hard-to-remove glossy labels on international deliveries; and owners of small offices who invested in a shredder but might have found this sufficient on its own. 'Having one of these is extremely convenient,' she said flatly.
Price, Colors, and Encyclopedia Entry
The suggested retail price is ¥1,100. The production staff found it online for ¥652 including tax, and depending on the retailer it can be found for under ¥500. The product comes in multiple colors; the unit in the studio was yellow-green.
